Abstract

Mode-locked fiber lasers emitting in the wavelength range beyond 2 μm are promising for a number of applications including environmental sensing, material processing, medicine etc. Ho-doped fiber lasers, though exploiting complicated pumping scheme in comparison with Tm/Ho-doped fiber lasers, allow laser emission at longer wavelength. Continuous-wave lasing at wavelengths up to 2.2 μm has been obtained in Ho-fiber lasers, but mode-locked operation has so far been only achieved at the wavelengths below 2.1μm [1] because of the lower gain and increasing optical losses in the fiber, making stable mode-locked laser action challenging.
