Chemical Lasers
Used as directed-energy weapons.
| Laser gain medium and type | Operation wavelength(s) | Pump source | Applications and notes |
|---|---|---|---|
| Hydrogen fluoride laser | 2.7 to 2.9 μm for Hydrogen fluoride (<80% Atmospheric transmittance) | Chemical reaction in a burning jet of ethylene and nitrogen trifluoride (NF3) | Used in research for laser weaponry by the U.S. DOD, 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 | MIRACL, Pulsed Energy Projectile & Tactical High Energy Laser |
| COIL (Chemical oxygen-iodine laser) | 1.315 μm (<70% Atmospheric transmittance) | Chemical reaction in a jet of singlet delta oxygen and iodine | Laser weaponry, scientific and materials research, laser used in the U.S. military's Airborne laser, operated in continuous wave mode, can have power in the megawatt range. |
| Agil (All gas-phase iodine laser) | 1.315 μm (<70% Atmospheric transmittance) | Chemical reaction of chlorine atoms with gaseous hydrazoic acid, resulting in excited molecules of nitrogen chloride, which then pass their energy to the iodine atoms. | Scientific, weaponry, aerospace. |

Famous quotes containing the word chemical:
“If Thought is capable of being classed with Electricity, or Will with chemical affinity, as a mode of motion, it seems necessary to fall at once under the second law of thermodynamics as one of the energies which most easily degrades itself, and, if not carefully guarded, returns bodily to the cheaper form called Heat. Of all possible theories, this is likely to prove the most fatal to Professors of History.”
—Henry Brooks Adams (1838–1918)
