Yk. Voronko et al., LASING AND SPECTROSCOPIC PROPERTIES OF CALCIUM-NIOBIUM-GALLIUM GARNETDOPED WITH TM3+, Kvantovaa elektronika, 20(4), 1993, pp. 363-365
Spectroscopic and lasing properties of CNGG-TM3+ crystals are investig
ated. The efficiency of the cross relaxation process has been determin
ed through Tm3+ luminescence decay curves. Stimulated emission at the
wavelength of 2.02 mum has been obtained on the F-3(4) --> H-3(6) tran
sition in CNGG Tm3+ at room temperature, the pulse generation energy b
eing 3.3 J.
