NOT KNOWN FACTS ABOUT HGGA2S4 CRYSTAL

With the appearance of recent nonlinear resources and one-frequency pump resources, there is renewed fascination in optical parametric oscillators (OPOs). Just one-method diode-laser-pumped monolithic Nd:YAG nonplanar ring laser which is each amplified and frequency doubled is accustomed to pump a monolithic MgO:LiNbO3 pulsed singly resonant OPO.We
