Second-harmonic generation of tunable CO2 laser radiation is reported and analyzed in ZnGeP2 both by angular and temperature tunings. Temperature tuning can thus be advantageously employed in this crystal for nonlinear devices.

    Abstract. Theoretical and experimental studies of phase-modulation effects in degenerate four-wave mixing are presented in this paper. Our experiments and analysis show that phase-modulation effects change the phase-matching condition and lead to a decrease in signal output and a degradation in...

    We propose a frequency converter which exploits laser pulses with changing state of polarization. The use of such pulses as a pump source for an extracavity doubling crystal is shown to result in the large conversion efficiency. These pulses can also provide a fairly good tool of monitoring the...
