Abstract

As reported recently [1], some of the infrared spectroscopic properties of Tm doped CaYAlO₄ such as a large and broad ³H₆ → ³H₄ absorption cross section (~ 1.5 × 10^-20 cm²) near 800 nm and a large and broad ³F₄ → ³H₆ stimulated emission cross section (~10^-20 cm²) near 1900 nm, are very attractive for tunable two-micron laser operation using diode pumping with relaxed diode wavelength control.
