Paper Abstract

We present spectroscopic properties and lasing results of Ho3+-doped Yttria (Y2O3), LuAG (Lu3Al5O12), and YAG (Y3Al5O12) at wavelengths beyond 1.6 μm. High resolution measurements of absorption and stimulated emission cross sections of Ho3+ in these hosts from 77K to 300K are reported. Laser operation based on 5I7 to 5I8 transitions of Ho3+ in these hosts is demonstrated.
