WHAT DOES HGGA2S4 CRYSTAL MEAN?

With the appearance of new nonlinear elements and single-frequency pump resources, There exists renewed desire in optical parametric oscillators (OPOs). Only one-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.A ma

The nonradiative transition costs Keep to the method WNR = W (0) exp(-alphap), the place p is the amount of phonons matching the Vitality hole. The nonradiative transition rates of Er3+ exhibit temperature dependence in step with the multiphonon peace concept. In Tm3+ the temperature dependence of nonradiative leisure rates is complex with the exis
