HGGA2S4 CRYSTAL FUNDAMENTALS EXPLAINED

With the appearance of latest nonlinear elements and single-frequency pump sources, There exists renewed fascination in optical parametric oscillators (OPOs). Only one-mode diode-laser-pumped monolithic Nd:YAG nonplanar ring laser which is equally amplified and frequency doubled is accustomed to pump a monolithic MgO:LiNbO3 pulsed singly resonant O
