FACTS ABOUT ER:YB:YAB CRYSTAL REVEALED

The nonradiative transition fees Adhere to the method WNR = W (0) exp(-alphap), in which p is the number of phonons matching the energy gap. The nonradiative transition fees of Er3+ show temperature dependence according to the multiphonon rest idea. In Tm3+ the temperature dependence of nonradiative relaxation premiums is difficult by the existence

The KTP crystal is usually a nonlinear optical product which can convert the frequency of light. The KTP crystal is Slice and oriented in this kind of way that it satisfies the section matching condition for 2nd harmonic era (SHG), which means that two photons from the input beam can combine to produce one photon of two times the frequency (or 50 %
