Robust 1.7-μm, all-polarization-maintaining femtosecond fiber laser source based on standard telecom fibers
摘要： We demonstrate a compact 1.7-μm all-polarization-maintaining (PM) ultrafast fiber laser source, which employs soliton self-frequency shift (SSFS) in an optical fiber as the dominant spectral-shifting mechanism. The laser generates stable pulses with 384 fs pulse width and 102 MHz repetition rate centered at 1.7 μm with 7 nm spectral bandwidth. The average power is about 35 mW with a high conversion efficiency of 66 %. The measured root mean square (RMS) output power stability over 10 hours is as low as 0.22 %. Both experimental and simulation results demonstrate that this laser has a potential to improving multiphoton imaging depth.

Tunable optical frequency comb from a compact and robust Er:fiber laser
摘要： We report on a compact and robust self-referenced optical frequency comb with a tunable repetition rate, generated by an all-polarization-maintaining (PM) mode-locked Er-doped fiber laser. The spacing between comb teeth can be tuned above 300 kHz at a repetition rate of 101 MHz. The repetition rate and the carrier–envelope offset of the laser are stabilized separately, and the relative residual phase noises are determined to be 336 μrad and 713 mrad (1 Hz–1 MHz). The accurate frequency characteristics and the stable structure show great potential for the use of such a comb in applications of precision measurements.

摘要： We demonstrate a compact all polarization- maintaining mode-locked femtosecond fiber laser with three different non-reciprocal phase shifters. The achieved laser directly delivers 926 fs, 0.56 nJ pulses at the repetition rate of 88.3 MHz.
