The soliton mode-lock fiber laser pulse energy dependence from saturable absorber parameters

We simulate passive mode-lock soliton like pulsing in Tm
³⁺
fiber laser with different saturable absorbers. The purpose of work was to find how the pulse highest energy for single pulse regime and mode-lock launching gain depends on the absorber. It is shown that the highest achievable energy in the same cavity can be reached with help of absorber that have highest saturation power and shortest relaxation time. Also we found dependences of the pulse energy, peak power, duration, spectrum width and time-bandwidth product value as gain increased until single pulse regime exist in cavity.
