WHAT DOES HGGA2S4 CRYSTAL MEAN?

With the appearance of latest nonlinear materials and single-frequency pump resources, There exists renewed interest in optical parametric oscillators (OPOs). Just one-method 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:LiNbO3 pulsed
