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

Abstract

We report a new design of an all-reflective 3rd-order frequency resolved optical gating setup (FROG) for measurement and characterization of ultrashort UV-pulses in the 230–350 nm spectral 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.
