Abstract

A high repetition rate excimer laser has been developed. The laser gas can be circulated at a flow rate of 120 m/s uniformly in the discharge region by a 4-stage axial blower. The recent results are presented on the XeCl laser operated stably at an ultra-high repetition rate of 4 kHz and an average power of 200 W in the condition of CR equals 3 with thinner He buffer gas mixtures. Above this repetition rate, the laser power saturates caused by the discharge constrictions. The residual charged particles probably induce this localized discharge instability, and Xe content has a harmful influence dominantly on the output power.
