SOLID STATE LASER AMPLIFIER.
Abstract
Observations of the spatial non-uniformities of laser gain indicated that the origin of this effect is laser light trapped within the ruby rod. Experimental and theoretical work with laser amplifier systems resulted in the development of a 3000 MW amplifier system. Systems with output half-power pulsewidths in the 50 - 250 microsec range were also developed. The limits of achievable performance were investigated, with allowances made for technologically feasible improvements and differing amplifier and oscillator component configurations. Amplification of the output of a curvedmirror interferometer was shown to be the most practical approach for producing high-brightness and spikeless laser output. Y2O3:Eu(+3) crystals of 1/4-inch diameter and one-inch length were grown. Difficulties encountered in lasing suggest the use of Gd(+3) as an additive ion. (Author)
