Abstract

We present guiding measurements of 0.8-μm, 100-fs pulses through LiF microcapillaries using discharge plasma. We inspect the transmission at conditions fit for soft-x-ray lasing. While up to 45% transmission is observed for input intensities of 1×1018 W/cm2, only ∼2% of the energy is contained in the small guided mode of 25 μm (FWHM). We investigate the dependence of the guiding on input intensity and focusing geometry. The transmission decreases for unmatched focal spots and as the intensity increases.

Density profiles at the microcapillary exit at different delays after discharge initiation. At 320 ns, a hollow waveguiding profile is produced with a matching beam diameter of 25 μm FWHM, after which the plasma density continues to rise.

Beam profile of a guided pulse. (a) Image of microcapillary exit; guided mode at center, microcapillary wall presented by white dashed curve. (b) Cross section of beam profile showing a Gaussian fit (dashed curve) with a diameter of 24 μm FWHM. (c) Two-dimensional intensity profile of beam at microcapillary exit.

Guided-beam intensity and spot size as a function of delay. Images of microcapillary exit at six different delays at top for f/5 geometry (image at 280 ns is enhanced to allow for visibility of spot). (a) Peak intensity for two different focusing geometries, f/5 and f/15. (b) Guided average spot size for the two different f-numbers. At 150 ns and earlier delays, there is no guided mode. There is an optimum timing for guiding, after which the spot size does not change but the transmission decreases.

Transmission of the guided beam as a function of the f-number. Transmission is peaked at f/15, which focuses the beam to the matching beam diameter. Shot-to-shot fluctuations in transmission were typically ±10% of the values indicated in the figure.

Fig. 6

(a) Transmission and (b) output intensity versus the input intensity. At the matching f-number (f/15) the decrease in transmission is not as steep as in the tightly focused case. Transmission is calculated relative to the energy contained in the 1/e2 spot size of the input beam.
