WHAT DOES HGGA2S4 CRYSTAL MEAN?

With the advent of new nonlinear materials and solitary-frequency pump sources, You can find renewed interest in optical parametric oscillators (OPOs). A single-mode diode-laser-pumped monolithic Nd:YAG nonplanar ring laser that's equally amplified and frequency doubled is utilized to pump a monolithic MgO:LiNbO3 pulsed singly resonant OPO.Just one
