Abstract
Strip buried heterostructure lasers were formed with a center‐to‐center spacing of 15 μm to give a densely packed monolithic linear array. Excellent uniformity in individual laser characteristics persisted across the entire array. The laser output power‐current characteristics of such arrays were linear and symmetric from both mirrors for the entire injection current range up to catastrophic damage. Pulsed‐out power of ∼1.6 W/mirror has been obtained for a five‐laser array. Spectral behavior of the arrays indicated that there was some field interaction between the neighboring lasers.Keywords
