THE BASIC PRINCIPLES OF HGGA2S4 CRYSTAL

With the advent of recent nonlinear elements and single-frequency pump sources, There may be renewed interest in optical parametric oscillators (OPOs). A single-mode diode-laser-pumped monolithic Nd:YAG nonplanar ring laser which is equally amplified and frequency doubled is utilized to pump a monolithic MgO:LiNbO3 pulsed singly resonant OPO.It has
