LITTLE KNOWN FACTS ABOUT HGGA2S4 CRYSTAL.

With the appearance of recent nonlinear elements and solitary-frequency pump resources, There may be renewed desire in optical parametric oscillators (OPOs). One-mode diode-laser-pumped monolithic Nd:YAG nonplanar ring laser that is definitely the two amplified and frequency doubled is utilized to pump a monolithic MgO:LiNbO3 pulsed singly resonant
