LITTLE KNOWN FACTS ABOUT HGGA2S4 CRYSTAL.

With the advent of new nonlinear elements and one-frequency pump resources, there is renewed interest in optical parametric oscillators (OPOs). An individual-method diode-laser-pumped monolithic Nd:YAG nonplanar ring laser that is certainly each amplified and frequency doubled is accustomed to pump a monolithic MgO:LiNbO3 pulsed singly resonant OPO
