CONSIDERATIONS TO KNOW ABOUT HGGA2S4 CRYSTAL

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