Abstract

We have obtained absorption spectroscopic cross sections as a function of wavelength for the laser material Ho:YAG at 295, 175, and 83 K, in the spectral range from 1700 to 2200 nm. The absorption range corresponds to I85I75 transitions from the ground state to the first excited state amenable to direct pumping by laser diodes and Tm fiber lasers. The data allow a direct comparison of the absorption cross-section intensities and linewidths as temperature is lowered from room temperature to cryogenic temperatures. Universal absorption curves and numerical tables are presented for pump sources that are assumed to have a Gaussian spectral lineshape, as a function of center wavelength, bandwidth, and optical density (doping density×penetration depth), at 295 and 83 K. Curves and tables are presented for both 295 and 83 K and may be used to optimize the pump absorption and laser efficiency.
