Clean, Few-Cycle, 7-fs Pulses Generated by PHAROS Laser
A research team in Hamburg generated nice, clean, few-cycle, 7-fs pulses from the cascaded multipass cells from a PHAROS laser from Light Conversion. Importantly, only dielectric mirrors are used. Overall transmission is over 80% and the 7-fs pulses are quite clean, having over 80% energy in the main peak. The system runs stably, thanks to the very stable PHAROS laser.
The abstract of this paper states:
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 were compressed by factor 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 ARPES, photoemission electron microscopy, and nonlinear spectroscopy.
