Experimental results of an electron beam-pumped XeF (C-A) excimer laser are presented and reviewed. Such a laser was operated with an optimized gas mixture of 8 At. Ar, 16 Torr Xe, 8 Torr NF3 for transverse excitation and 2 At. Ar, 8 Torr Xe, 3 Torr NF3 for longi-itudinal pumping. In patieular, the influence of the optical resonator configuration upon the broadband wavelength tuning and enhanced output power characteristics was studied. With longitudinal electron beam excitation a tuning range of 74 nm (from 455 nm to 529 nm) accompanied by spectral narrowing has been demonstrated. The linewidth of the laser emission is-5nm when a prism is used as the dispersive element and is reduced even further to-lnm when the prism is replaced by a diffraction grating.

The dispersion produced by an ordinary single stack cavity mirror is analysed. This kind of mirror is difficult to compensate the upehirp of the pulses in the cavity. A kind of double ooated stack mirror, with the suitable amount of dispersion of φ(ω) =1.3 ×10~(-28) sec2 for upchirp compensation is designed and used as cavity mirrors, so that pulses as short as 30 fs are generated directly from a simple oolliding-pulse modo-locked (CPM) dye laser without additional dispersive elements in the cavity.
