An XeF(C {r arrow} A) laser, pumped at a rate of 290 kW/cm{sup 3} with a 600 ns electron-beam pulse, has been operated as an injection-controlled oscillator. A stable cavity has been injected with radiation from a pulsed dye laser source. A significant reduction in laser turn-on time has been achieved, and the laser pulse duration has been extended to 500 ns (FWHM). As a consequence, the laser intrinsic efficiency and specific output energy have been increased by approximately 50%, to 1.8% and 3 J/L, respectively, which represent the best performance obtained thus far for any directly electrically-excited XeF(C {r arrow} A) laser. Also, by injecting a narrowband signal into the cavity, the XeF(C {r arrow} A) laser linewidth has been reduced by more than two orders of magnitude, to less than 1.3 {Angstrom}, the resolution of the spectrometer. The laser wavelength has been tuned from 478.6 to 486.8 nm, with less than a factor of two variation in output energy.
