CONSIDERATIONS TO KNOW ABOUT HGGA2S4 CRYSTAL

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