Optically Pumped Carbon Monoxide Cascade Laser
Abstract
The experimental and theoretical results of an optically pumped vibrational CO laser are explored. A tunable 1550-1580nm optical parametric oscillator laser was used as a pulsed pump source. The OPO pumped the R(6) through R(9) (3,0) overtone band of the CO, which induced lasing on the (3,2) and (2,1) bands around 4.7% The laser output was spectrally separated to determine the spectral and temporal evolution of the CO lasing pulse. The influence of CO pressure, cell length, pump pulse intensity, and the resonator Q-Factor on the CO laser pulse temporal profile and spectral distribution were studied. A numerical model was developed, and the experimental results are compared to the model predictions.
