The Longest Wavelength OPO Pumped by a 1µm Laser


Singly resonant type-il AgGaS2OPO yielded continuously tunable 3.9–11.3 µm idler output with slope quantum efficiency up to 41 % (absolute photon efficiency 22%). The OPO has sub-100 µJ threshold pump energies for nanosecond 1.06µm Nd:YAG laser pulses.
