“…Thulium tervalent ions have long fluorescence lifetimes, high quantum efficiency and the absorption of thulium ter valent ions is near 790 nm which matches well with the commercially laser diodes [6]. Various 2 μm solid state lasers based on Tm doping crystal, such as Tm:YAG, Tm:YLF, Tm:KLu(WO 4 ) 2 , Tm:KYW and Tm:YAP have been studied and reported [7][8][9][10][11][12][13][14][15][16][17].…”

A diode end pumped single frequency Tm:GdVO 4 laser at room temperature was reported. The maximal output power of single frequency is as high as 66 mW by using two uncoated fused etalons, which are respectively 0.05 mm thick YAG and 1 mm thick quartz. We obtained the single frequency Tm:GdVO 4 laser at 1875.1 nm. The slope efficiency is 1.5%. The change of the lasing wavelength on temperature was also measured. The single longitudinal mode (SLM) laser can be used as a seed laser for coherent wind measure ments and differential absorption LIDAR systems.

“…The trivalent thulium ion (Tm 3+ ) which has laser transition at about 1.9 μm ( 3 F 4 3 H 6 transition) has attracted more and more attention for its wide tunabil ity and high efficiency [10][11][12][13], especially its absorp tion peak at about 800 nm corresponding to 3 H 6 3 H 4 transition is suitable for commercial laser diode GaAlAs pumping [14]. It had been reported that Tm 3+ doped materials present good laser performance [15⎯18].…”

A Tm, Mg co doped LiTaO 3 crystal has been grown by Czochralski method. Room temperature polarized absorption spectra and fluorescence spectrum of the Tm, Mg:LiTaO 3 crystal were measured and analyzed. The maximum absorption cross section is 6.0791 × 10 -20 cm 2 at around 790 nm with full width at half maximum of 5 nm. The emission cross section of 3 F 4 manifold was 2.2 × 10 -20 cm 2 . The spectroscopic parameters of Tm 3+ ion were calculated by applying the Judd-Ofelt approach, and the intensity parameters Ω 2 , Ω 4 , and Ω 6 were obtained to be 7.71 × 10 -20 , 1.09 × 10 -20 , and 1.16 × 10 -20 cm 2 , respectively. The branch ing ratios and radiative lifetimes were also presented and the radiative lifetime of Tm 3+ 3 F 4 3 H 6 transition is 968.3 μs. The results were also analyzed and compared with other Tm 3+ doped hosts.
