LITTLE KNOWN FACTS ABOUT HGGA2S4 CRYSTAL.

With the appearance of recent nonlinear elements and solitary-frequency pump resources, You can find renewed interest in optical parametric oscillators (OPOs). A single-mode diode-laser-pumped monolithic Nd:YAG nonplanar ring laser that may be both of those amplified and frequency doubled is used to pump a monolithic MgO:LiNbO3 pulsed singly resona
