NOT KNOWN FACTS ABOUT HGGA2S4 CRYSTAL

With the advent of new nonlinear resources and one-frequency pump resources, There's renewed curiosity in optical parametric oscillators (OPOs). Just one-mode diode-laser-pumped monolithic Nd:YAG nonplanar ring laser that is certainly both equally amplified and frequency doubled is used to pump a monolithic MgO:LiNbO3 pulsed singly resonant OPO.A m
