THE BASIC PRINCIPLES OF HGGA2S4 CRYSTAL

With the advent of latest nonlinear components and single-frequency pump resources, There may be renewed fascination in optical parametric oscillators (OPOs). Just one-mode diode-laser-pumped monolithic Nd:YAG nonplanar ring laser which is equally amplified and frequency doubled is used to pump a monolithic MgO:LiNbO3 pulsed singly resonant OPO.It'
