Environmentally-stable 50-fs pulse generation directly from an Er:fiber oscillator
Abstract
We report on a long-term stable 50 fs pulse generation directly from a nonlinear amplified loop mirror based fiber oscillator. The laser cavity with all-polarization-maintaining fiber components can generate pulses with 0.16 nJ pulse energy and 50 fs pulse width under 85 MHz repetition rate. The 0-45 °C high-low temperature test, together with the 15 h output power test, shows the excellent stability of the few-cycle pulsed laser.
