title: Injection behavior of high-power broad-area diode lasers.
abstract: A single-mode diode laser is injected into a high-power broad-area diode laser to produce single-mode operation with 80 mW in a 0.50 degrees-wide far-field lobe. Spectrally resolved near- and far-field measurements suggest a simple Fabry-Perot amplifier model that qualitatively explains the observed injection and beam-steering behavior in these devices as well as gain-guided multiple-stripe arrays. This model provides criteria for the optimization of injection performance.
