Abstract

Continuous-wave 1.5-μm-band laser is demonstrated in thulium doped tellurite glass microsphere by single laser pumping. 1.9-μm laser from the lower transition (3F43H6) of Tm3+ is generated to depopulate the lower level (3F4) of 1.5-μm transition (3H43F4) in order to achieve the population inversion. Laser wavelength of 3H43F4 transition is shifted by 30 nm from the emission peak. Slope efficiency of 1.9-μm laser is improved after the1.5-μm laser starts to lase.
