Xr. Zou et al., SPECTRAL CHARACTERISTICS OF MINIATURE 2-LONGITUDINAL-MODE OPTICALLY PUMPED FIR LASER, International journal of infrared and millimeter waves, 19(11), 1998, pp. 1561-1570
With the assumption that the pump source was two-longitudinal-mode, th
e semiclassical density matrix equation of a three-energy-level system
was solved. By means of iteration method, the spectral characteristic
s of miniature two-longitudinal-mode optically pumped NH, far-infrared
cavity laser, which was pumped by CO2-9R(16) line, were calculated nu
merically. The influences of operating parameters on laser spectrum we
re studied intensively.
