Net anomalous dispersion all-PM Yb-doped fiber laser producing high energy sub-100 fs pulses
Fiber Lasers XIX: Technology and Systems(2022)
摘要
We present the first all-polarization-maintaining Ytterbium-doped fiber laser oscillator mode-locked through a nonlinear optical loop mirror that works in a dispersion-managed dissipative soliton regime. Using a chirped fiber Bragg grating, we built a cavity of a net negative dispersion delivering ultrashort 2.3 nJ pulses at a repetition rate of 34.08 MHz. Chirped 3.96 ps pulses from the oscillator are recompressible down to 98 fs with a high temporal Strehl ratio.
