AbstractWe report the 1.03 μm laser operation of a diode-pumped Yb doped YAG planar waveguide at room temperature. The fabrication of multilayer planar waveguides by Liquid Phase Epitaxy and their characterization are also described.Laser results (40 mW threshold, 80 % slope efficiency) obtained with a 2.9 % output coupler compares favourably with bulk results reported elsewhere.

We report on thermal analysis and a continuous wave (CW) laser operation at (1.998µm) of end pumped Tm: YAP cylindrical laser rod. The Tm: YAP laser rod is pumped at a wavelength of 1.064 µm emitting from Nd: YAG laser source. A 3W incident pump power is used to generate a maximum laser output of 700 mW, representing 18% slope efficiency. The power of thermally induced lens in Tm:YAP laser rod is numerically analyzed and validated experimentally. The focal lengths of the thermally induced lens are directly measured using Shack-Hartmann wavefront sensor. We have detected blue up-conversion fluorescence emission before laser operation at 1.998 µm. The obtained experimental results were in good agreement with the numerical calculations.
