High power, short pulse acousto-optically Q-switched fibre laser
High power, short pulse acousto-optically Q-switched fibre laser
Short pulse, high peak power Q-switching of fibre lasers is demonstrated using a specially constructed TeO2 acousto-optic modulator with high diffraction efficiency at 1.06µm. The laser emits > 0.7 kW peak power pulses with 2.8ns duration at up to 1 kHz repetition rates for an absorbed pump power of 13 mW under zeroth order operation with average rf power of 50 mW. Under first order operation we obtained > 150 W peak power pulses with a 4ns duration using average rf driving power of 0.5 mW. Exact numerical integration of the laser kinetic rate equations yields good agreement with the experimental results.

Abstract
Short pulse, high peak power Q-switching of fibre lasers is demonstrated using a specially constructed TeO2 acousto-optic modulator with high diffraction efficiency at 1.06µm. The laser emits > 0.7 kW peak power pulses with 2.8ns duration at up to 1 kHz repetition rates for an absorbed pump power of 13 mW under zeroth order operation with average rf power of 50 mW. Under first order operation we obtained > 150 W peak power pulses with a 4ns duration using average rf driving power of 0.5 mW. Exact numerical integration of the laser kinetic rate equations yields good agreement with the experimental results.
