High-resolution line-shape analyses of the pulsed cuprous chloride-laser oscillator and amplifier
Abstract
A high resolution Fabry-Perot interferometer is used to measure the time-averaged spectral line shapes of the a-hyperfine component of the CuI 5782-A line generated by a pulsed, high gain CuCl laser. The high power oscillator, low power oscillator, oscillator-amplifier and spontaneous emission source operational modes are studied using a quasi-steady state approximation and a gain-switched pulsed model for the oscillator and amplifier, respectively. Experimental and computed interferograms are fitted by varying the unsaturated gain, saturation, and spontaneous emission parameters, whose values are found to agree with those obtained by other methods. The total average spectral output of the high power oscillator is found to be about 6.7 W, with an unsaturated gain of 0.15/cm.
