NOT KNOWN FACTS ABOUT HGGA2S4 CRYSTAL

With the appearance of recent nonlinear resources and solitary-frequency pump sources, there is renewed interest in optical parametric oscillators (OPOs). An individual-method 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
