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 (³F_4->³H₆) of Tm³⁺ is generated to depopulate the lower level (³F ₄) of 1.5-μm transition (³H _4->³F₄) in order to achieve the population inversion. Laser wavelength of ³H_4->³F ₄ transition is shifted by 30 nm from the emission peak. Slope efficiency of 1.9-μm laser is improved after the 1.5-μm laser starts to lase.
