Abstract: We report on the crystal growth, structural and spectroscopic investigation of a novel trigonal calcium vanadate crystal, Tm3+:Ca9La(VO4)7. Polarized absorption, stimulatedemission and gain cross-section spectra are determined for this material. The maximum ¿SE corresponding to the 3F4 ¿ 3H6 transition amounts to 1.28 × 10-20 cm2 at 1854 nm for ¿- polarization. The measured lifetime of the Tm3+ ions in the 3F4 state is 1.19 ms. The Judd- Ofelt analysis performed yielded intensity parameters of ¿2 = 4.682, ¿4 = 0.659 and ¿6 = 0.475 [10-20 cm2]. The polarized Raman spectra indicate a strong and broad band centered at 867 cm-1. Owing to the disordered nature of Ca9La(VO4)7, the Tm3+ ions exhibit a broad and smooth gain profile at ~2 ¿m. The spectroscopic properties of Tm3+:Ca9La(VO4)7 are very promising for broadly tunable and ultrashort pulse lasers near 2 ¿m.
