Abstract

A laser gun uses small arms technology for loading and firing a cartridge containing flash powder. When the cartridge is fired, the flash powder burns to produce an intense burst of light. This light is directed for optically pumping a laser medium that emits an intense pulse of laser light. The cartridge-based small arms technology allows the gun to be easily and conveniently carried about and fired rapidly and reliably.

Claims

1. In a small arms type laser gun, a small arms type cartridge for use in a small arms size cartridge chamber of the laser gun, said cartridge comprising:

a. a casing adapted to fit within the small arms cartridge chamber, the casing being charged with a chemically combustible flash material that emits an intense light when burned;

b. a retainer confining said flash material within an output end of said casing;

c. a primer arranged within a primer end of said casing;

d. said primer end of said casing having a rim arranged for limiting the entry of said casing into the cartridge chamber; and

e. detonation of said primer being arranged to initiate chemical combustion of said flash material for blowing expanding and light-emitting gases from said output end of said casing as said flash material burns so that light emitted from said gases is directed forward of the cartridge chamber where it is effective for pumping a predetermined laser medium.

2. The small arms type cartridge of claim 1 wherein the output end of the casing and a discharge end of the cartridge chamber are arranged at an end of the casing opposite the primer.

3. The small arms type cartridge of claim 1 wherein the composition of the flash material is selected such that the spectrum of radiation emitted by the material when it is burned is optimized for optically pumping the laser medium.

4. The small arms type cartridge of claim 1 wherein said flash material is held in said casing by a binder.

5. In a small arms type laser gun, a small arms type cartridge comprising:

a. a combustible flash material configured in a shape that fits into a small arms size cartridge chamber of the small arms type laser gun;

b. a primer assembled with the flash material and positioned so that ignition of the primer in response to the striking action of a small arms type firing pin of the small arms type laser gun initiates rapid burning of the combustible flash material; and

c. the cartridge having an output end aligned with a discharge opening of the cartridge chamber when the cartridge is inserted into the cartridge chamber so that the burning flash material is directed through the output end of the cartridge and the discharge opening to a region of the small arms type laser gun forward of the cartridge where light from the burning flash material pumps a predetermined laser medium.

6. The small arms type cartridge of claim 5 including a binder for the flash material.

7. The small arms type cartridge of claim 5 further comprising a casing containing the flash material and the primer.

8. The small arms type cartridge of claim 7 further comprising a rim that limits the insertion of the cartridge into the cartridge chamber of the small arms type laser gun.

9. The small arms type cartridge of claim 7 wherein the output end of the cartridge is sealed to retain the flash material.
