Comment on ’’Dynamic model of high-pressure rare-gas excimer lasers’’

Abstract

The model of the rare‐gas excimer lasers that was recently proposed by Werner et al. is shown to be inconsistent with some experimental measurements of xenon dimer laser gain and laser intensity. Measurements of the laser intensity and laser‐medium gain of a xenon dimer laser show that the laser pulse terminates well before the laser‐medium gain falls below the prelasing losses of the optical resonator. The measured value of the stimulated‐emission cross section for the xenon dimer laser is (1.05±0.2) ×10⁻²⁵ A cm² at 1720 Å, where A is the transition probability of the upper energy level of the laser.
