Abstract

By splicing on a length of Ho³⁺-doped silica fiber onto a diode-pumped double-clad Tm³⁺-doped silica fiber, stable passive Q switching of the Tm³⁺-doped silica fiber laser is demonstrated. The formation of Q-switched pulses was found to depend on both the length and the position of the Ho³⁺-doped silica fiber that was inserted into the fiber laser cavity. For stable Q-switched pulse generation, Ho ³⁺-doped silica fiber lengths shorter than twice the absorption depth must be used. For long Ho³⁺-doped silica fiber lengths, randomly generated pulses are observed at operating wavelengths longer than 2090 nm, which are attributed to intracavity pumping of the Ho³⁺-doped silica fiber.
