Abstract
For several years now picosecond dye laser technology has served researchers in the investigation of ultra-short phenomena. While becoming more and more sophisticated, synchronously pumped dye lasers today are a standard research tool in many laboratories. There exists however a substantial range of applications - mainly for instance in the short wavelength range or in non-linear applications - where these lasers do not provide sufficient pulse energy or peak powers. The answer to this problem has been the develop-ment of picosecond pulse amplifiers which can bring the low intensity pulses from a mode-locked laser to high intensities followed possibly by frequency doubling and maybe even further amplification after the doubling stage. While such systems have led to excellent results they have at the same time excluded experimenters who are not interested in spending time and energy in the development of such comparatively complex laser systems from doing research in this area. To these researchers, the Lambda Physik PSL 4000 makes available for the first time a turn-key laser of modest complexity which can deliver pulses in the ultraviolet spectral region at 248 and 308nm with durations of the order of a few 10 picoseconds and energies of the order of 10 mJ or more. With this instrument focussed intensities which exceed 1014Wcm-2 can be achieved using standard optics.
