LITTLE KNOWN FACTS ABOUT HGGA2S4 CRYSTAL.

With the arrival of recent nonlinear components and solitary-frequency pump resources, There's renewed fascination in optical parametric oscillators (OPOs). Only one-manner diode-laser-pumped monolithic Nd:YAG nonplanar ring laser which is each amplified and frequency doubled is utilized to pump a monolithic MgO:LiNbO3 pulsed singly resonant OPO.Ou
