NOT KNOWN FACTS ABOUT HGGA2S4 CRYSTAL

With the appearance of recent nonlinear components and single-frequency pump resources, There exists renewed interest in optical parametric oscillators (OPOs). Just one-mode diode-laser-pumped monolithic Nd:YAG nonplanar ring laser that's the two amplified and frequency doubled is accustomed to pump a monolithic MgO:LiNbO3 pulsed singly resonant OP
