Abstract
The characteristics of a Q-switched neodymium-doped double-clad fiber laser were presented. Based on the proposed differential equations with suitable boundary and initial conditions, a numerical model was developed to simulate this fiber laser. All the calculations were based on wave-travelling approach. Using this model, pulse duration and the energy of generated pulses can be predicted. In the experiment, pulses with the energy of 0.36mJ (84ns) and 154μJ (48ns) at the repetition rate of 500Hz were achieved for 5 and 3-m long fiber, respectively. The extractable energy was limited due to low energy storage and the fiber-end facet damage. The results obtained numerically agree well with the experimental results.
