LITTLE KNOWN FACTS ABOUT HGGA2S4 CRYSTAL.

With the arrival of recent nonlinear components and one-frequency pump resources, You can find renewed curiosity in optical parametric oscillators (OPOs). A single-method diode-laser-pumped monolithic Nd:YAG nonplanar ring laser which is both amplified and frequency doubled is used to pump a monolithic MgO:LiNbO3 pulsed singly resonant OPO.One obse
