Measurement and characterization of sub-5 fs broadband UV pulses in the 230-350 nm range

Abstract

We report a new design of all-reflective 3rd-order frequency resolved optical gating setup (FROG) for measurement and characterization of ultrashort UV-pulses in the 230-350 nm range and tested it using 7.3 fs pulses generated in the 250-300 nm range. This setup allows also heterodyne detection which significantly increases its sensitivity
