WHAT DOES HGGA2S4 CRYSTAL MEAN?

With the arrival of recent nonlinear components and single-frequency pump resources, There is certainly renewed interest in optical parametric oscillators (OPOs). An individual-manner diode-laser-pumped monolithic Nd:YAG nonplanar ring laser that is definitely both of those amplified and frequency doubled is accustomed to pump a monolithic MgO:LiNb
