NOT KNOWN FACTS ABOUT HGGA2S4 CRYSTAL

With the appearance of new nonlinear materials and single-frequency pump resources, You can find renewed desire in optical parametric oscillators (OPOs). Just one-mode diode-laser-pumped monolithic Nd:YAG nonplanar ring laser which is each amplified and frequency doubled is utilized to pump a monolithic MgO:LiNbO3 pulsed singly resonant OPO.Output
