Abstract

Cryogenic temperature operation of a c-cut Tm(5%),Ho(0.3%):YAlO3 laser end-pumping by a fiber-coupled laser-diode is reported. A 2.55 W incident pump power is used to generate 160 mW of laser output, representing a 7.1% optical-to-optical conversion efficiency respect to the incident pump power. In the experiment, three wavelengths—2.04, 2.10, and 2.13 µm oscillation have been observed simultaneously, which is agreement with the inherent a-axis polarization fluorescence spectra of Tm,Ho:YAlO3. Also single wavelength oscillation performance has been observed which is centered at 2.13 µm.
