Abstract
A diode laser array consisting of three initially uncoupled stripes is injection-locked by a 50 mW single-mode frequency tunable diode laser. Phase-conjugation is achieved by pumping a photorefractive crystal by the beams emitted from the master oscillator and the slave laser array. The injected beam is phase-conjugated with respect to the beam emitted by the slave diode laser array. The pumping beam from the slave laser is spatially filtered by a slit in the far field in the slow axis using a collimating lens. The slit consists of two mirrors, which act also as the output couplers.
