LITTLE KNOWN FACTS ABOUT HGGA2S4 CRYSTAL.

With the advent of latest nonlinear supplies and one-frequency pump sources, You can find renewed curiosity in optical parametric oscillators (OPOs). An individual-method diode-laser-pumped monolithic Nd:YAG nonplanar ring laser that is the two amplified and frequency doubled is accustomed to pump a monolithic MgO:LiNbO3 pulsed singly resonant OPO.
