Multiline injection mode locking of a transversely excited atmosphere CO2 laser

Abstract
A multiline injection mode locked transversely excited atmosphere CO2 laser has been operated for use in high intensity laser‐plasma interaction experiments. Laser pulses of 390 MW and 2‐ns duration with up to three equal power lines were produced by installing intracavity SF6 cells in both the injection and slave oscillators to tune them to the desired laser transition. A simple model defines the laser system requirements to achieve simultaneous oscillation on several lines.
