Few-cycle pulse compression and white light generation in cascaded multipass cells

We report supercontinuum generation and pulse compression in two stacked multipass cells based on dielectric mirrors. The 230 fs pulses at 1 MHz containing 12 µJ are compressed by a factor of 33 down to 7 fs, corresponding to 1.0 GW peak power and overall transmission of 84%. The source is particula...

Zusammenfassung:We report supercontinuum generation and pulse compression in two stacked multipass cells based on dielectric mirrors. The 230 fs pulses at 1 MHz containing 12 µJ are compressed by a factor of 33 down to 7 fs, corresponding to 1.0 GW peak power and overall transmission of 84%. The source is particularly interesting for such applications as time-resolved angle-resolved photoemission spectroscopy (ARPES), photoemission electron microscopy, and nonlinear spectroscopy.
