EXPERIMENTS RELATING TO REGENERATIVE LASER AMPLIFIER DESIGN.
Abstract
Experiments and calculations are reported in efforts to determine the applicability of multiple reflection concepts to laser amplifier design. The data indicates at least qualitative agreement with proposed theories in that it is shown that if the regenerative amplifier is pumped with too much energy the amplification will decrease. Estimates of the population inversion of the amplifier show that as the pump light from the Xenon source irradiates the ruby crystal, the attenuation constant increases in the amplifier before amplifier oscillations appear, during the period of oscillations, and even after the amplifier oscillations cease. However, as the time between the quenching of the oscillation of the amplifier and the arrival of the input signal increases, the gain decreases. This effect is consistent with the multiple reflection theory. (Author)
