Injection-beam parameter optimization of an injection-locked diode-laser array.
The dependence of the far-field distribution of an externally injection-locked array on the width and power of the injected beam was determined by numerical simulation. The fraction of total power contained in the diffraction-limited lobe portion of the far field was significantly larger for wide-beam injection (95%) than for single-point injection (70%). Qualitative agreement with experimental results using a 20-element array was observed.
