This dataset contains experimental data for the paper:


The figures are as follows:

Fig. 1  Experimental Schematic of the Mamyshev oscillator (MO).

Fig. 2  Output characteristics of the MO. (a) pulse train; 
(b) output power (blue diamond markers) and pulse energy (orange circle markers) vs. 
absorbed pump power; (c) output spectra at different output power; 
(d) Autocorrelation function (ACF) of the output. 

Fig. 3  (b) SEM image of the AR-HCF cross-section with a 20 μm scale bar. 
(c) AR-HCF characteristics including attenuation (orange curve) and 
simulated group velocity dispersion (GVD, blue curve); 
the blue dashed line marks the zero-dispersion point. 
The grey curve shows the broadest MO output spectrum used in the experiment. 
(d) Far-field beam profile of the AR-HCF output, exhibiting a near-Gaussian mode shape. 
The noise pattern in the beam image is likely originating from interference caused by 
the thin-film filter mounted in front of the camera sensor. 

Fig. 4  Power delivery of the AR-HCF based compressor. 
(a) input energy (circle markers), output energy (diamond markers) vs. pulse spectral bandwidth;
(b) overall efficiency vs. pulse spectral bandwidth.

Fig. 5   (a) grating-based compression(green solid line), 
AR-HCF (cut-back) compression (circle markers) results and its fitting (blue dashed curve) vs. 
transform-limited calculation (dashed curve); 
(b) input spectrum (green curve) and output spectrum (orange curve) of the AR-HCF at highest peak power; 
(c) ACF of pulse compressed by AR-HCF (purple solid curve) and grating pair (green solid curve) 
and transform-limited result (dashed curve).
