Simplified laser system for the generation of 60 fs pulses at 248 nm.

Abstract

A simplified hybrid excimer-dye laser system is described, capable of generating subpicosecond pulses at most of the excimer laser wavelengths. In this paper ≈ 60 fs pulse generation is reported at 248 nm, using the above system and additional pulse compression. The effect of the operational conditions of different parts of the system and of the compressor on the spectral and temporal characteristics of the output pulse is studied
