3 W of single-frequency output at 532 nm by intracavity frequency doubling of a diode-bar-pumped Nd:YAG ring laser

Abstract

A beam-shaped 20-W diode bar has longitudinally pumped a Nd:YAG laser in a ring configuration. Unidirectional single-frequency operation is enforced by a Faraday rotator. Intracavity frequency doubling with a KTP crystal has produced 3 W of stable single-frequency TEM₀₀ output at 532 nm.
