Gain measurement of Cd recombination lasers.
Gain measurement and characteristics of an IR laser in Cd I at 1.65-microm (4f(3)F(4)-5d(3)D(3)) and 1.43-microm (6p(3)P(1)-6s(3)S(1)) transitions over a range of discharge parameters in a sealed discharge tube, based on a segmented plasma excitation and recombination scheme, are presented. Maximum gain observed for the 1.65-microm transition is 0.0087 cm(-1) at the optimum operating conditions of the laser.
