THE BASIC PRINCIPLES OF HGGA2S4 CRYSTAL

With the arrival of recent nonlinear materials and one-frequency pump sources, There may be renewed fascination 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 utilized to pump a monolithic MgO:LiNbO3 pulsed singly resonant OPO.
