NOT KNOWN FACTS ABOUT HGGA2S4 CRYSTAL

With the advent of latest nonlinear resources and single-frequency pump resources, You can find renewed curiosity in optical parametric oscillators (OPOs). Just one-mode diode-laser-pumped monolithic Nd:YAG nonplanar ring laser that's both amplified and frequency doubled is utilized to pump a monolithic MgO:LiNbO3 pulsed singly resonant OPO.1 obser
