Efficient continuous wave and broad tunable lasers with the Tm:GdScO 3 crystal
Résumé
The spectroscopic properties and tunable laser performances of the orthorhombic perovskite Tm:GdScO 3 crystal grown by the Czochralski method are comparatively studied for polarization along different crystallographic axes. The polarized emission spectrum of Tm:GdScO 3 along the b -axis exhibits, to the best of our knowledge, the broadest bandwidth among all the single Tm 3+ -doped bulk gain media, indicating the strong inhomogeneous line broadening of Tm 3+ ions in GdScO 3 and thus leads to a broad and smooth gain spectrum. Tunable laser operation with a tuning range as broad as 321 nm from 1824 nm to 2145 nm is achieved, which indicates its potential for few-optical-cycle pulse generation in the 2-µm spectral range.
