THE BASIC PRINCIPLES OF HGGA2S4 CRYSTAL

With the arrival of latest nonlinear elements and single-frequency pump sources, There is certainly renewed curiosity in optical parametric oscillators (OPOs). Just 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.
