Observation of stimulated emission in KrCl

Research output: Contribution to journalArticlepeer-review


Stimulated emission at 222.9±0.1 nm in KrCl has been observed in electron-beam-excited Ar/Kr/Cl2 mixtures. Approximately 50 kW of laser output in a 30-ns pulse with ∼14% output coupling has been obtained. Both the peak spontaneous emission wavelength and vibrational spacing (ωe) of KrCl* are in agreement with the alkali-halide analog (RbCl) model. The kinetics of this new rare-gas-halide laser molecule are briefly discussed.
