THE BASIC PRINCIPLES OF HGGA2S4 CRYSTAL

With the arrival of recent nonlinear resources and one-frequency pump sources, There exists renewed desire in optical parametric oscillators (OPOs). Just one-method 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.The sign
