WHAT DOES HGGA2S4 CRYSTAL MEAN?

Optical parametric oscillator pumped at ~one µm with intracavity mid-IR distinction-frequency era in OPGaAsA method-locked tunable dye laser is made which is synchronously pumped at substantial repetition rates because of the doubled output of a method-locked Nd:YAG laser. The dye laser gives rigorous pulses of 35 psec length which can be greatly
