Abstract
Pulsed laser operation in αβHo:YLF and αβHO:YAG at λ = 2.1 μm in the temperature range 83-220 K is described. A similar dependence of threshold energy on temperature is seen in both crystals. A broad maximum in laser energy and slope efficiency at about 150 K is found in αβHo:YLF. This behaviour is explained by Boltzman population and back transfer from Ho(III) to Er(III) and Tm(III).
