HGGA2S4 CRYSTAL NO FURTHER A MYSTERY

With the arrival of recent nonlinear elements and one-frequency pump sources, There is certainly renewed fascination in optical parametric oscillators (OPOs). Only one-method diode-laser-pumped monolithic Nd:YAG nonplanar ring laser that is both amplified and frequency doubled is used to pump a monolithic MgO:LiNbO3 pulsed singly resonant OPO.A met
