Abstract

The electron-beam excited XeF(C→A) laser is broadly tunable by means of injection-control and has the potential for a relatively high efficiency as well as narrow band width operation [1]. However, efficient broadband tuning is impaired by absorption from transient species and decreasing gain in the wings of the XeF(C→A) gain profile. Recent experiments have shown that the transient absorbers appear to be saturable through the use of an intense injection laser pulse [2]. Using a long pulse coaxial flash lamp pumped dye laser as an injection source, continuous wavelength tuning has been achieved between 470 and 500 nm with a spectral width of 0.6 nm. Wavelength tunability to both shorter and longer wavelengths will also be discussed.
