Abstract

A polarization multiplexing method (based on Sagnac interferometer's principle) was used in combination with a table-top wide aperture discharge pumped excimer amplifier to amplify femtosecond UV pulses. It is possible to optimize the operational conditions of the device within a wide range of input energies by changing the optical setup, while keeping the signal-to-noise ratio (short pulse - amplified spontaneous emission (ASE) ratio) of the pulses on a reasonably low value. The amplifier was tested for two different front ends. With ∼40μJ input energy ∼50 mJ output energy was obtained in a 3-pass arrangement, and applying a seed pulse carrying an energy of around 2-3 mJ a maximum output energy of 100 mJ was reached in a single subpicosecond beam at 248 nm.
