Optical parametric oscillator pumped at similar to 1 mu m with intracavity mid-IR difference-frequency generation in OPGaAs

Intracavity difference-frequency generation (DFG) between signal and idler pulses is investigated in orientation-patterned GaAs inside the cavity of a similar to 1 mu m pumped nanosecond optical parametric oscillator (OPO). Using two different samples and temperature tuning in the non-critical confi...

Description
Summary:Intracavity difference-frequency generation (DFG) between signal and idler pulses is investigated in orientation-patterned GaAs inside the cavity of a similar to 1 mu m pumped nanosecond optical parametric oscillator (OPO). Using two different samples and temperature tuning in the non-critical configuration, tunability between 7 and 9.2 mu m is demonstrated. The superior thermo-mechanical properties of OPGaAs enabled also for the first time operation of this cascaded scheme at kilohertz (1-3 kHz) repetition rates reaching average powers similar to 10 mW in the mid-IR.
