The obtain bandwidth e.g. of Yb:KGW and Yb:KYW may be very huge when compared with that of Yb:YAG. This enables for extensive wavelength tunability and for A lot shorter pulse durations from mode-locked lasers. Values very well below a hundred fs are reached with passive manner locking.The Yb-doped potassium yttrium tungstate (Yb:KYW) crystal, in … Read More

The nonradiative transition fees Adhere to the formula WNR = W (0) exp(-alphap), wherever p is the quantity of phonons matching the energy gap. The nonradiative changeover prices of Er3+ exhibit temperature dependence in step with the multiphonon relaxation principle. In Tm3+ the temperature dependence of nonradiative peace premiums is intricate th… Read More
