16 fs Pulse Generation and Measurement in the Ultraviolet and Vacuum Ultraviolet
We present measurements of ultrafast third (266 nm) and fifth (160 nm) harmonic light in gases. The pulse duration of the third harmonic is measured at under 16 fs, using the technique of self-diffraction frequency resolved optical gating. To date, the 3ω conversion efficiency (up to 0.2%) is the largest measured for sub-100 fs pulses. These pulses are the shortest UV pulses generated and characterized.
