Multi-regimes electronically controlled all-fibre PM ANDI F8 laser

Abstract

An all-normal dispersion figure-of-eight fibre laser which provides generation of qualitatively different pulse generation regimes (single-scale and double-scale pulses) by the electronical tuning of two laser diodes pump powers is present for the first time. Electronical tuning of the pump powers also allows one to change and control parameters of the pulse generation (pulse duration, power and energy) in a wide range for each started regime. In particular, the possibility of changing the pulse duration by a factor of 2 for each pulse generation mode is shown, and the total range of tuning by the duration of the autocorrelation function of pulses is from 30 to 100 ps. And also for the first time the possibility of an increase by a factor of 8 of the peak power of the output pulses is shown with an increase in the pulse energy from 2 to 16 nJ and at a fixed duration of the autocorrelation function of pulses of 55 ps.
