ABSTRACT:
An apparatus and method for pumping a gas laser, wherein a field emitter is sed to emit electrons into the gas to effect laser pumping. The low energy electrons emitted by field emitters, and the fine controllability of electron energy permitted by field emitters, enables one to effect population inversion of the laser gas, without ionizing the gas, or causing electrical breakdown.
