Abstract

Spectral broadening in gas-filled hollow-core fibers is discussed for sulfur hexafluoride, a molecular gas with Raman activity. Experimental results for compressed pulses are presented for input pulses longer than the Raman period and shorter than the dephasing time at a central wavelength of 800 nm and 400 nm, respectively. For both wavelengths we compress the pulses by a factor of three and maintain a good pulse quality. The obtained results are of interest for compressing pulses generated with Yb doped lasers.

Figures (6)

Fig. 1
Fig. 1

Comparison of spectral broadening in a argon (a) and SF6 (b) filled HCF for different gas pressures. Parameters of the input laser pulses and the HCF remain unchanged (see text). A normalization was done for the output pulse energy of the HCF and the resulting spectral intensity is shown in a logarithmic color scale. For SF6 the generation of Raman sidebands is observed by vertical lines with higher amplitude at fixed positions and corresponds to the A1g vibrational mode as indicated by the dotted lines. Above the pressure scans outlines at 1000 mbar for both gases are depicted.

Fig. 2
Fig. 2

Spectral broadening in a SF6-filled HCF for different laser input pulse energies (a) and different pulse durations (b) for a fixed gas pressure of 1000 mbar. The input energy was varied using neutral density filters, while the pulse duration was constant at 78 fs. In (b) the pulse duration was varied by positively chirping the spectrally unchanged lasers pulse, which had 850 µJ pulse energy.

Fig. 3
Fig. 3

Measurement of spectrally broadened pulses after prism compressor: (a) Using 300 mbar SF6 a broadening to 57.2 nm (FWHM) is observed. After compression a residual cubic spectral phase remains. (b) The temporal profile shows the main- and post-pulse separated by 38 fs. The main pulse contains 94% of the energy and has a duration of 26fs, compared to 15fs of the less energetic post-pulse. The spectral phase and temporal profile were retrieved from a GRENOUILLE measurement.

Measurement of the beamprofile: Raw image and lineouts in horizontal and vertical direction of a spectrally broadened pulse after compression using two prisms. The effective diameter of the collimated beam is 5.01 mm.

Fig. 5
Fig. 5

Comparison of spectral broadening in argon (a) and SF6 (b) for laser pulses with 400 nm wavelength. Due to the reduced peak power compared to experiments in Fig. 1 just SPM occurs for both gases. However in case of SF6 reduction of the HCF transmission becomes dominant at pressure levels above 400 mbar indicated by the intensity drop in the logarithmic color scale.

Fig. 6

Interferometric autocorrelation trace for spectrally broadened and compressed pulses at 400 nm central wavelength: The pulse duration is in the order of 23.3fs and due to missing SRS no post-pulses occur.
