Optimisation of the pulse duration of a discharge pumped XeF (B-X) excimer laser

摘要

In an x-ray preionised XeF(B→X) discharge-excited laser driven by a magnetic-spiker sustainer circuit with a magnetic pulse compressor the influence of the various parameters on the optical pulse duration was experimentally investigated. Laser pulses at λ = 351 nm with a duration of 212 ns (FWHM) have been achieved in a NF3/Xe/Ne mixture by using very low (0.25 mbar) NF3 partial pressures in a total gas pressure of 2.5 bar and with a high-reflecting output coupling mirror.
