HGGA2S4 CRYSTAL - AN OVERVIEW

With the advent of new nonlinear supplies and single-frequency pump sources, There exists renewed curiosity in optical parametric oscillators (OPOs). Only one-mode diode-laser-pumped monolithic Nd:YAG nonplanar ring laser that is both equally amplified and frequency doubled is used to pump a monolithic MgO:LiNbO3 pulsed singly resonant OPO.The sign
