Threshold studies of pulsed confocal unstable optical parametric oscillators

Rise Time of Pulsed Parametric Oscillators

Gain saturation of an Nd-glass amplifier by 1.06-pmlight pulsesis determined by the lifetimes and degeneraciesof thetwo laser states aswell a s by thermalization rates among the com-ponents of the twomultiplets to which thelaserlevels belong.Reportedaremeasurements showing thatalthoughsmall signalgain was the same foramplified micr...

Continuous-wave Optical Parametric Oscillators

Since the publication of an earlier review on optical parametric oscillators (OPOs) in 2000,1 there has been remarkable progress in the technological development and applications of OPO devices. Once considered an impractical approach for the generation of coherent radiation, OPOs have now been finally transformed into truly viable, state-of-the-art light sources capable of accessing difficult ...

2 . 2 Intra - cavity difference frequency generation in pulsed optical parametric oscillators

Tunable 35to 38-THz wave generation by difference frequency was demonstrated. An optical parametric oscillator (OPO) and intra-cavity difference frequency generator (iDFG) were used as the light source for difference frequency generation (DFG) of 30to 38THz waves. The iDFG consisted of two nonlinear periodically poled lithium niobate (PPLN) devices: one was for the OPO and the other was for DFG...
