We present the progress made in developing IOPW OPCPA facility for the Vulcan laser to produce pulses with focused intensities >1023 Wcm-2. This power level will be delivered by generating pulses with >300J in 30fs. These pulses will be delivered to

The 2ω 0 and 3ω 0 /2 emitted radiation from 0.53 μm ablative compressions is used to study the uniformity of illumination by the six beams RAL Vulcan laser under different focussing conditions. Results are found to be in reasonable agreement with

The contrast ratio of the recompressed output pulses in an optical parametric chirped pulse amplification system can be limited by temporal noise on the pump pulse. We present a simple analysis which can be used to estimate both the contrast ratio of

Broad-band amplification of femtosecond laser pulses using the scheme of noncollinear optical chirped pulse parametric amplification is modeled. The effect of two-photon absorption at the pump wavelength was also taken into account. The signal pulses

Broadband amplification of laser pulses at 400 nm is demonstrated with a maximum gain of 3550 using non-collinear optical parametric amplification. Without depleting the pump, the spectral gain was found to be almost flat along the available 17-nm-wi

Frequency doubling a 140 × 110 mm 40 J sub-ps 1054 nm beam for laser matter interaction studies was investigated at the Central Laser Facility, with efficiencies greater than 60% being achieved. The conversion characteristics (efficiency, beam quali

The wavelength resolved spectra recorded during subnanosecond depletion of the gain in a KrF laser amplifier have been used to specify the state responsible for the dip in the KrF(B→X) emission spectra. Self-absorption of the KrF laser emission at

Bandwidth and efficiency have been measured in a series of experiments of type II mixing of previously chirped 50 fs pulses. It has been found that if the input pulses have chirps of opposite sign, the bandwidth of the generated pulse can be broader

This paper presents an experimental technique for measurement of the contrast ratio of ultrashort UV pulses. As a multiple-shot device based on the scheme of difference frequency generation this is, to our knowledge, the only cross correlator in the
