![عکس صفحه اول مقاله: Growth, spectroscopic properties and laser performance near 2 µM of Tm3+/Ho3+: SrGdGa3O7 crystal Growth, spectroscopic properties and laser performance near 2 µM of Tm3+/Ho3+: SrGdGa3O7 crystal](/preview/png/5428072.png)
- The spectroscopic properties of Tm3+/Ho3+: SrGdGa3O7 were studied for the first time.
- The crystal exhibited a broad absorption band and a broad emission band.
- The crystal has a long fluorescence lifetime of 5I7 multiplet (Ho3+) up to 8.0Â ms.
- The 2.0 µm laser has been realized with the a-cut and c-cut crystal samples.
The Tm3+/Ho3+: SrGdGa3O7 single crystal was grown by the Czochralski method. The polarized absorption spectra, emission spectra and fluorescence decay curves of the crystal were measured. The crystal exhibited a broad absorption band and a broad emission band, as well as a fluorescence lifetime of 5I7 multiplet of Ho3+ ions up to 8.0 ms. End-pumped by a fiber-coupled diode laser at 808 nm, the laser operation around 2.0 µm has been realized with the a-cut and c-cut crystal samples. The maximum output power is 200 mW when a-cut crystal sample was employed.
