Stimulated emission in gallium phosphide
Abstract
Second-harmonic emission from a Q-switched neodymium laser was used to stimulate emission at the A equals LO exponent x line in gallium phosphide at 77.3 K. The half-width of the line increased from 5 to 10 meV with increased pumping intensity in the interval (1-3) times 10 to the 24th per sq cm per sec, then decreased to 5 meV as pumping intensity was increased to about 10 to the 25th per sq cm per sec.
