Little Known Facts About HgGa2S4 Crystal.
Optical parametric oscillator pumped at ~1 µm with intracavity mid-IR difference-frequency generation in OPGaAsA mode-locked tunable dye laser has long been produced which can be synchronously pumped at significant repetition fees through the doubled output of the method-locked Nd:YAG laser. The dye laser gives intensive pulses of 35 psec period w
