Abstract

By using a new mutually pumped phase-conjugation setup consisting of two photorefractive crystals, a broad-area three-stripe diode laser is locked to a single-mode diode laser at a drive current up to 2.25 times the threshold current. The bandwidth is narrowed from about 2 nm to 0.034 nm, with an available output power of 1.5 W.
