Title: Lasing characteristics of ZrO{sub 2}–Y{sub 2}O{sub 3}–Ho{sub 2}O{sub 3} crystal

The spectral dependences of the gain cross section of the {sup 5}I{sub 8} → {sup 5}I{sub 7}, {sup 5}I{sub 7} → {sup 5}I{sub 8} transition of Ho{sup 3+} ions in the ZrO{sub 2} – 13.6 mol % Y{sub 2}O{sub 3} – 0.4 mol % Ho{sub 2}O{sub 3} crystal are calculated at different relative population inversions using the absorption and luminescence spectra of the {sup 5}I{sub 8} → {sup 5}I{sub 7} and {sup 5}I{sub 7} → {sup 5}I{sub 8} transitions of Ho{sup 3+} ions at T=''300'' K. Lasing of these crystals at the {sup 5}I{sub 7} → {sup 5}I{sub 8} transition is obtained for the first time under pumping by a Tm : YLiF{sub 4} laser (λ{sub p} = 1.905 μm). The lasing wavelength is 2.17 μm. (lasers)
