HGGA2S4 CRYSTAL SECRETS

With the arrival of recent nonlinear products and solitary-frequency pump resources, there is renewed interest 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 OPO.1 o
