Abstract

The process of high harmonic generation allows for coherent transfer of infrared laser light to the extreme ultraviolet spectral range opening a variety of applications. The low conversion efficiency of this process calls for optimization or higher repetition rate intense ultrashort pulse lasers. Here we present state-of-the-art fiber laser systems for the generation of high harmonics up to 1 MHz repetition rate. We perform measurements of the average power with a calibrated spectrometer and achieved µW harmonics between 45 nm and 61 nm (H23-H17) at a repetition rate of 50 kHz. Additionally, we show the potential for few-cycle pulses at high average power and repetition rate that may enable water-window harmonics at unprecedented repetition rate.

Generic setup used for high harmonic generation. The driving laser is focused onto a gas jet (Xe, Kr, Ar). The harmonic beams is separated from the fundamental by two 200 nm aluminum filters (400 nm overall thickness). The spectrum is measured with a calibrated spectrometer.

Fig. 5

Interaction geometries used for high harmonic generation with a nonlinear compressed FPCA system. An f=150 mm, f=200 mm and f=300 mm focal lens have been used. The peak intensity for f = 300 mm has been obtained via the cutoff law, while for shorter focal lengths (f=150 mm, f=200 mm) we scaled the peak intensity via the focal spot sizes.

Spectra of high harmonics obtained with a nonlinear compressed FPCA by using different focal length lenses and krypton (a) and argon (b) gas. The y-axis of each spectrum corresponds to the normalized counts obtained on the camera. Please note that the signal increase below 25 nm is due to the enhanced sensitivity of the spectrometer and does not correspond to more conversion into this region.
