All polarization-maintaining assively mode-locked yb-doped fiber laser : pulse compression using an anomalous polarization-maintaining photonic crystal fiber
Abstract: We report the generation of short pulses at 1 μm using an all-polarizationmaintaining (PM) fiber configuration. The pulses are provided by an all normal-dispersion Fabry-Perot Yb-doped cavity and are compressed with an anomalous polarizationmaintaining photonic crystal fiber (PM PCF)....

| Sumario: | Abstract: We report the generation of short pulses at 1 μm using an all-polarizationmaintaining
(PM) fiber configuration. The pulses are provided by an all normal-dispersion
Fabry-Perot Yb-doped cavity and are compressed with an anomalous polarizationmaintaining
photonic crystal fiber (PM PCF). Opposed to standard configurations; here
the filtering action is solely performed by the finite bandwidth of the gain medium. The laser
generates 8 ps width sech2 profile pulses at 1046.8 nm with a −10 dB bandwidth of 5.9 nm.
After compression using the PM PCF, pulses with an FWHM of 3 ps were obtained, limited
by the actual value of the available anomalous dispersion. We also report the changes in
the output light pulses when both the net-normal dispersion of the cavity and the medium
gain length were varied. We found that the lack of a specific filter within the cavity does not
deteriorate the performance as compared with previous works. |
