✦ Synopsis

A new discharge design for pulsed CO2 lasers has been made with a series of short longitudinal synchronous discharges working at high pressure with large section. In this way, single-mode high-power (up to 40 kW at 100 ns) tail-free pulses have been obtained at intermediate repetition frequency (25 Hz) in a He-free mixture dominated by CO2 (75 -90% content). This laser is ideal for producing frequency mixing in non-linear crystals.
