摘要：

The spectroscopic properties of Tm3+ ions in Ca-3(VO4)(2) crystal were investigated and diode pumped tunable lasing was demonstrated. The maximum absorption and emission cross-sections for E perpendicular to c at F-3(4) H-3(6) 2 mu m transition were calculated to be similar to 1 x 10(-20) cm(2) and similar to 1.3 x 10(-20) cm(2) respectively. Noticeable H-3(4) F-3(4) H-3(6) F-3(4) cross-relaxation was observed resulting in a slope laser efficiency up to 15% at similar to 1960 nm under 792 nm laser diode pumping. Broadband tuning of the oscillation wavelength within the 1850-2070 nm spectral range was realized.
