WHAT DOES HGGA2S4 CRYSTAL MEAN?

With the appearance of new nonlinear products and single-frequency pump resources, There exists renewed desire in optical parametric oscillators (OPOs). A single-manner diode-laser-pumped monolithic Nd:YAG nonplanar ring laser that may be equally amplified and frequency doubled is used to pump a monolithic MgO:LiNbO3 pulsed singly resonant OPO.We r
