Abstract

We report attainment of transform-limited bandwidth in an XeF laser by injection locking a positive-branch confocal unstable resonator with 1 W of power from an Ar-ion laser at 3511 Å. A diffraction-limited beam of >2-MW power, with a bandwidth of ~50 MHz (~1 × 10⁻⁴ Å), is generated. We find that since the XeF UV emission lines start from different upper vibrational levels of the B state, ~40% of the B → X energy is not available to be channeled into the locked line.
