Device for injection-seeding, frequency-shifting, and q-switching a laser source

摘要

This invention is an optical device for laser sources, particularly for injection-seeded laser sources. The invention is an acousto-optic element used within a laser cavity to satisfy three functions-injection-seeding, frequency-shifting, and Q-switching. Use of this device rather than separate devices for each function increases reliability and lowers cost, while providing a large injection-signal into the laser cavity.
