Revealing Influence of Timing Jitter on Ultrafast Raman Fiber Laser Synchronously-pumped by Gain-switched Diode

The "fig3" folder: "1 o'clock", "2 o'clock", and "3 o'clock" are all measured by an oscilloscope, representing the time-domain characteristics of the output Raman pulse duration at 48.4 ps, 69.5 ps, and 187.9 ps. The "1st frequency", "2nd frequency", and "3rd frequency" are all measured by a spectrometer, representing the spectral characteristics when the output Raman pulse duration is 48.4 ps, 69.5 ps, and 187.9 ps. The "1 autocorrelation", "2 autocorrelation", and "3 autocorrelation" are all measured by autocorrelation instruments, representing the autocorrelation characteristics when the output Raman pulse duration is 48.4 ps, 69.5 ps, and 187.9 ps. The "3 spectra" represent the spectral characteristics measured by the spectrometer when the pulse duration is 187.9 ps. The "fig4" folder: "A spectrum" and "B spectrum" were both measured by a spectrometer, representing the spectral characteristics of 1065 nm pump pulses before and after stretching. Both "A autocorrelation" and "B autocorrelation" were measured by an autocorrelation meter, representing the autocorrelation characteristics of 1065 nm pump pulses before and after stretching. The "B frequency domain" is measured by a spectrometer and represents the RF characteristics of 1065 nm pump pulses. The "B time domain" is measured by an oscilloscope and represents the time domain characteristics of 1065 nm pump pulses. The "fig5" folder contains the measured RIN spectra of the output Raman pulses at 48.4 ps, 69.5 ps, and 187.9 ps when using GSD as the pumping source; And the RIN spectrum when a mode-locked laser is used as a synchronous pump source. And background noise. There are also four situations corresponding to RIN integral. RIN is measured by a spectrometer. Folder "fig6": Synchronous pumped Raman fiber laser system pumped by 9-cavity Yb doped mode-locked laser: pump spectra, autocorrelation. Raman spectroscopy, spectra, pulse sequences, and autocorrelation data. All data were processed using Origin.
