Abstract

The initial experimental results of an injection-seeded unstable cavity F2 laser, of which the small-signal gain-length product was about 29, was described. In particular, the performance of injection seeding in a discharge-pumped F2 laser in which amplified spontaneous emission (ASE) governed the output at the free-running condition because of the extremely high gain was investigated. The injection-seeding efficiency and the beam quality were found to deteriorate at the later part of the laser pulse due to the failure of the optical component from the seed pulse to exceed the ASE during the entire laser pulse. However, the beam divergence of the output laser beam was improved by a factor of about 4.3 by employing the injection-seeding scheme compared to the free-running stable cavity.
