Experimental investigation of double-clad Tm3+-doped silica fiber amplifying at 1.99μm

摘要：

The LD-clad-pumped CW and Q-switched pulse Tm3+-doped silica fiber amplifiers were general experimental investigations. The CW fiber amplifier provided up to 3W output with the slope efficiency nearly 30％, and the Qswitched pulse fiber amplifier output power was 2W with the slope efficiency 32.6％. The gain fiber was 27.5/400μm Dshaped Tm3+-doped silica double-cladding fiber, and the pump sources was a 792nm LD with a 400μm pigtail fiber output. The signal seed sources was a LD-pumped Tm3+:YAP lasing at 1.99μm. By the AO Q-switched method, The Tm3+:YAP laser had a nearly 120ns pulse duration and 1kHz repeat rates. The measured amplified spectrum only stretched a little relative to the input signal spectrum.
