NOT KNOWN DETAILS ABOUT HGGA2S4 CRYSTAL

With the advent of new nonlinear materials and single-frequency pump resources, There's renewed interest in optical parametric oscillators (OPOs). Only one-manner diode-laser-pumped monolithic Nd:YAG nonplanar ring laser which is both amplified and frequency doubled is accustomed to pump a monolithic MgO:LiNbO3 pulsed singly resonant OPO.It's got l
