Type: article
Abstract: We report a 1100 nm all-polarization-maintaining (all-PM) fiber laser based on gain-managed nonlinear amplification (GMNA), and demonstrate its capability for in vivo two-photon imaging. The home-built fiber oscillator functioned using a nonlinear amplification loop mirror (NALM), delivering a 38.1 MHz, 13.8 mW, 1024 nm signal laser. The pre-chirp management (PCM) was incorporated with GMNA to enable efficient nonlinear amplification. The system ultimately generated pulses with an energy of 110 nJ and a duration of 56 fs, with the corresponding 10 dB spectral range spanning from 1041 nm to 1117 nm. This 1100 nm ultrafast fiber laser provides a convenient light source for multi-photon microscopy (MPM).
