Chemical reaction in a burning jet of ethylene and nitrogen trifluoride (NF 3) Used in research for laser weaponry, operated in continuous-wave mode, can have power in the megawatt range. Deuterium fluoride laser ~3800 nm (3.6 to 4.2 μm) (~90% atm. transmittance) chemical reaction US military laser prototypes. COIL (chemical oxygen–iodine laser)
Organic lasers are inherently tunable and when configured as optimized multiple-prism grating laser oscillators can yield efficient single-transverse mode, and single-longitudinal-mode, emission with laser linewidths as narrow as 350 MHz (approximately 0.0004 nm at a wavelength of 590 nm), in the high-power pulsed regime.
A commercial laser for cutting materials uses a motion control system to follow a CNC or G-code of the pattern to be cut onto the material. The focused laser beam is directed at the material, which then either melts, burns, vaporizes away, or is blown away by a jet of gas, [1] leaving an edge with a high-quality surface finish. [2]
Burn and surgical scar management: scar contracture CO 2 (especially the newer fractionated CO 2 lasers), redness and itch (Pulsed Dye laser - PDL), post-inflammatory hyper-pigmentation (Q-switched lasers :Ruby, Alexandrite), burn scar unwanted hair growth and trapped hairs (Ruby, IPL and numerous hair removal lasers)
Liquid-crystal lasers are comparable in size to diode lasers, but provide the continuous wide spectrum tunability of dye lasers while maintaining a large coherence area. The tuning range is typically several tens of nanometers. [1] Self-organization at micrometer scales reduces manufacturing complexity compared to using layered photonic ...
Meanwhile, a lower power HF laser was used for the THEL (Tactical High Energy Laser) built in the late 1990s for the Israeli Ministry of Defense in cooperation with the U.S. Army SMDC. It is the first fielded high energy laser to demonstrate effectiveness in fairly realistic tests against rockets and artillery.
A chemical oxygen iodine laser (COIL) is a near–infrared chemical laser. As the beam is infrared, it cannot be seen with the naked eye. It is capable of output power scaling up to megawatts in continuous mode. [citation needed] Its output wavelength is 1315 nm, a transition wavelength of atomic iodine.
The Vulcan Laser, part of the Central Laser Facility onsite at the Rutherford Appleton Laboratory, Oxfordshire. The Vulcan laser is an infrared, 8-beam, petawatt neodymium glass laser at the Rutherford Appleton Laboratory's Central Laser Facility in Oxfordshire, United Kingdom. It was the facility's first operational laser.
