THE BASIC PRINCIPLES OF HGGA2S4 CRYSTAL

With the advent of latest nonlinear elements and solitary-frequency pump sources, there is renewed fascination in optical parametric oscillators (OPOs). An individual-manner diode-laser-pumped monolithic Nd:YAG nonplanar ring laser which is both amplified and frequency doubled is accustomed to pump a monolithic MgO:LiNbO3 pulsed singly resonant OPO
