Active Q-Switching in Different Fiber Laser Circuits

Moscow University Physics Bulletin Aims and scope

Abstract

The effect of a laser structural circuit on the efficiency of a periodic active Q-switching regime is demonstrated by using a fiber laser based on active bismuth centers as an example. The numerical simulation of different circuits makes it possible to understand some details of the formation of a multipeak output signal structure and, in many cases, to increase the efficiency of Q-switching, retaining a single output pulse, which saturates the active medium maximally deeply. For this purpose, the Q-switching method based on a short-term multiple increase in the Q-factor in each time period is proposed. As shown by calculations, such a method enables the generation of single pulses with a duration of nearly 0.01 from the time of a single pass through a resonator.
