Abstract

LiNbO₃ is an attractive and widely used dielectric medium in integrated optics. An optimisation of the laser action performance from a diode-pumped Yb³⁺ doped LiNbO₃:MgO crystal has been carried out. The results are compared to those obtained under the same experimental conditions on Nd doped LiNbO₃ crystals. It is concluded that thermal loading is higher in Nd:LiNbO₃ mainly because of the larger quantum defect between pump and laser photons.
