摘要：
We studied the mode instability (MI) of the signal light in high power all-fiber amplifier with large-mode-area (LMA) gain fiber experimentally. The MI phenomenon of the output beam was observed and analyzed in the all fiber amplifier, and the MI power threshold was compared by coiling gain fiber with different radii in multi kilowatt level (more than 3 kW). In the experiments, MI power threshold was improved and optimized with coil radius reduction of the LMA gain fiber in the all-fiber amplifier.
