摘要

We present a simple method for producing Q-switched pulses in an erbium-doped fibre laser (EDFL) ring configuration using molybdenum aluminium carbide (Mo3AlC2) as a saturable absorber (SA). Solution-casting method is used to create the Mo3AlC2-based SA. After increasing the pump power from 45.45 to 76.75 mW, a stable Q-switched pulses at 1558 nm were produced. The highest repetition rate recorded was 53.76 kHz, the smallest pulse width was 5.93 μs, and the highest pulse energy was 41.48 nJ.
