LITTLE KNOWN FACTS ABOUT HGGA2S4 CRYSTAL.

With the appearance of new nonlinear products and one-frequency pump sources, there is renewed desire in optical parametric oscillators (OPOs). An individual-manner diode-laser-pumped monolithic Nd:YAG nonplanar ring laser that is certainly each amplified and frequency doubled is accustomed to pump a monolithic MgO:LiNbO3 pulsed singly resonant OPO
