Magnetic self pinching allows the beam to recover somewhat from the scattering beam spread, but not entirely. Means to make these abuses visible and recognized as crimes by local, county/parish, state and federal legislators and law enforcement alike. The beam energy is 4.8 kJ per shot, with a sustained fire rate of 5 full energy beams per second, and can safely handle up to an additional 14 full energy beams worth of overheating. further penetration is dependent on the ability to open a hole in tissue 6 cm lens. with lasers) you need to deposit enough energy onto a point on the Yes, and this is a problem if you want to push the penetration much above the 30cm I specified. beam in your guts. ), (no, you haven't. Just install a switchable mirror that flashes reflective for the millisecond the beam is on, and you could then direct the light from your target that comes into your weapon's optics straight into an eyepiece. That's why they call them "vacuum frequencies", they work best in vacuum. Since you have constant drilling speed, and a typical cross section across the human body is 25 cm, you will be getting that force over about 1/3 of a millisecond. ISAAC KUO: Even if we're using a wavelength that is blocked by the eye, diffuse radiation from the hot target spot might be a problem. Not that slow. There is still the The cornea, lens, and vitrous humor of the eye are transparent to wavelengths between roughly 0.35×10-6 and 1.4×10-6 meters, lasers using these wavelengths can cause blindness. I suppose you could put it on This is the wrong term to use, but I am unsure what the right one is. In search of the ultimate in infantry-portable enemy-slaying goodness, Stavatti have one-upped all previous attempts by proposing to use a radioisotope generator containing 750 grams of Polonium-210. In the role playing game Traveller, laser carbines are powered by a large battery worn in a back pack. ANTHONY JACKSON: You can cut down on it by a lot by using frequencies that don't pass Chaka deserved to be killed, but death would have turned him into a martyr and strengthened the hold of his regime. Now, lets say our beam hits a human, with a cross section of 5 square millimeters when it hits, and we'll assume a penetration depth of 5 cm2, for a total affected volume of 0.25 cubic centimeters, or 2,000J/cm3. that the safe level is 10% of the 50% damage threshold, so the 50% Liquified gas, generally nitrogen or one of the noble gases which would not themselves erode the metal, was therefore released into the bore after every shot. That said, they don't worry about it much for military applications, either, because you have to be a very good, very cocky sniper with an amazingly good gun to successfully hit a target that small in just the right way to break through the deliberately-hardened-against-this-scenario shell and fracture the loops. Many of the visitors ask if they can hold it. Article 2: In the employment of laser systems, the High Contracting Parties shall take all feasible precautions to avoid the incidence of permanent blindness to unenhanced vision. energy point per game-turn segment for 20 segments (thin-film Li-ion with no tech improvements From Table 5, the optimal wavelength windows for molecular atmospheric absorption are between 1.03 μm and 1.06 μm, and around 1.241 and 1.624 μm. That's why single shot A drastic lowering of the power requirements. Besides the double stack of rounds, At higher energies you get radiative losses beginning to dominate, and this will not change with increasing ionization. It looks to me like they expect 25% to 50% of the energy of a Li-ion “I looked at what’s known about pulsed RF/MW in relation to diplomats’ experiences,” said Golomb. battery pack when you are hiding behind cover, switching between An important fact to note is that the laser medium has to be "pumped" by filling it with a higher energy/shorter wavelength compared to the laser beam that will emerge. Since I assumed by lasers were 50% efficient, all the previously stated beam powers are too large by a factor of 2 (and the details on the pulse trains which I retro-fitted to give the right beam power will be off as well). Note that a typical person will be about 20 cm to 30 cm through the torso (depending on orientation), so this pulse would not only shoot through a person, but through the guy behind him as well. It is likely that this image does not represent the upper limit of the of a threat to eyesight as the muzzle flash of Serious disability is equivalent to visual acuity of less than 20/200 Snellen measured using both eyes. The input parameters chosen for the simulation runs are meant to represent likely operational scenarios for ship self defense against a cruise missile attack. A long-gun-size directed energy weapon. Imagine if the room the target was in suddenly found itself loaded with 1,000 more people. Kerr points out a flashlight can cut through steel as well, IF it is very powerful and very close (making up for the lack of coherent light and optics). Of course, the direct damage may not mean much; 5 cm penetration isn't really enough to kill anything (I'm not sure how the secondary X-rays will be distributed, or what energy level they're at, but the secondary radiation may be quite adequate to disrupt the nervous system). are also "high capacity power packs" with three times the specific And recoilless, stabilized automatic fire should allow a moderately capable marksman to walk a burst on target in one or two reaction cycles (say, half a second) in most circumstances. slower). shape, so it doesn't need to stick out so much. An ethics concern has been raised for the use of this weapon against people with … The beams used really do vaporize their targets, with all the attendant thermodynamics, so best wear a shielded suit when firing unless you want your front half to be blackened cajun-style. Blasters use a clever technique to avoid this. back in the general direction of Johnson. This is about a 15 speck of dirt on the window can create a burn spot on the glass, which In-particular, I played with HITRAN's buggy API for a while until I figured out they don't actually have data on the whole spectrum. A The outer barricade had fallen, and now a wave of reptilian forms flooded into the control room. In an atmosphere, radiation will scatter off air molecules to irradiate things near the beam. Her conclusions, she said, may aid in the treatment of the diplomats (and affected family members) and assist U.S. government agencies seeking to determine the precise cause. It flashes, then you have to wait for the "charged" light to come on before the strobe will flash again. Put maybe 0.1 seconds between the safety pulse and Some SF novels have postulated one-shot power modules. Dr. Schilling assumes that in the near future rechargable batteries will reach an energy density of 2.5 kilojoules per cubic centimeter (2.5×109 J/m3). Beam divergence for a near-IR laser (such as neodymium-doped yttrium aluminium garnet (Nd:YaG)) can be estimated as on the order of 1mm per (aperture in mm) meters, and focus tighter than 1-2mm is probably not useful due to issues of hole aspect ratio, so the range at which these weapons would retain full penetration is reasonable for their apparent roles (as assault rifle, SMG, pistol), though rather sharply capped as compared to conventional rifles (which, while not very effective beyond a few hundred meters, don't drop to irrelevance). I will also confess that my suspension of disbelief took a slight knock when I got to the bit about the TIS-1 also sporting a bayonet lug. retina to cause third degree burns, fast enough that heat conduction And it possesses a unique and priceless natural feature: the extinct volcano known as the Zambue Crater. Water is all body tissue. For a more stringent requirement of at least 99% transmittance, the suitable wavelength windows are between 1.03 to 1.06 μm and around 1.241 and 1.624 μm. The best is 1000 nanometers (1e-6 m) because it will go through pretty much anything that is transparent to visible light. ends up looking like a camcorder or camera lens or some such. Patent US7784390B1 - Solid-state non-lethal directed energy weapon There is disclosed a solid state non-lethal directed energy weapon. though at the power levels proposed it won't be very loud; probably Energy is measured in Joules (J, refer to the Boom Table). Since higher energy pulses explode to give bigger craters, higher energy beams will have longer range for the same primary aperture. A beam of light that will drill a hole through armour plate, or carry a message as far as Pluto—which was the job the Mark X had been designed for—would give a man only a painful but quite superficial burn. Your 0.26 cm spot size is 0.05 cm2, so the dirty air limit is around 107W or 10J/microsecond. The conversion of the Soviet defense industry caused the project to be cancelled. The highly reflective dielectric Winchell Chung, but note that with the listed specific power of 1.322 kW/kg, to get your 6 kJ laser to shoot even one time per second you will need a 4.5 kg battery. It cannot penetrate window glass but quartz is transparent to UV. Don't forget to double the spot radius in order to get the spot diameter. Loaded down with Delgonian weapons they hurried back the way they had come. This means each square mm has to deal with a smaller fraction of the total laser energy. capacitor pack worn on the belt or as a backpack, a connection near kJ beams at full power, and draw 10 kJ. Another clever one would be to use the laser's optics to project a laser sight. dangerous if it is intense enough, but less so than a collimated So you could get fifty to a hundred shots from a pistol-sized non rechargeable energy source, or half that with a rechargeable battery. clean, you peel it off.
