Abstract

We report on the generation of powerful sub-20 fs deep UV pulses with 10μJ level energy and broadly tunable in the 250310nm range. These pulses are produced by frequency doubling a high-power noncollinear optical parametric amplifier and compressed by a pair of MgF2 prisms to an almost transform-limited duration. Our results provide a power scaling by an order of magnitude with respect to previous works.

Retrieved temporal and spectral intensity and phase of typical SD-FROG measurements at (a), (b) 255 nm and (c), (d) 290 nm . The measured pulse durations were 20.0 fs and 19.8 fs , and the errors of the FROG retrieval was 0.009 for 255 nm and less than 0.005 for 290 nm at a grid size of 128 × 128 .
