NOT KNOWN FACTS ABOUT HGGA2S4 CRYSTAL

With the appearance of recent nonlinear components and solitary-frequency pump resources, There may be renewed curiosity in optical parametric oscillators (OPOs). One-manner diode-laser-pumped monolithic Nd:YAG nonplanar ring laser that is each amplified and frequency doubled is used to pump a monolithic MgO:LiNbO3 pulsed singly resonant OPO.It's g
