Abstract
Room temperature operation of a c-cut microchip Tm,Ho:Lu2SiO5 laser end-pumping by a fibercoupled laser-diode is reported. A 4.03 W incident pump power is used to generate a maximum laser output of 98 mW, representing 2.43% optical-to-optical conversion efficiency and a 4.38% slope efficiency corresponding to incident power. In the experiment, the oscillating wavelengths shifting from 2.084 to 2.089 μm has been observed and approximately 10 mW single 2.087 μm wavelength oscillation has been obtained by changing the pump power to 1.43 W and the position of the pump focus.
