High‐power leaky‐mode multiple‐stripe laser

A new multiple‐stripe injection laser has been developed. By fabricating a stripe array of buried heterostructures configured to operate in leaky modes, strong coupling is produced between the stripes leading to linear operation and stable output characteristics. Efficient utilization of the total emitting area results from leaky‐mode operation, and peak pulsed output powers to 1.5 W have been observed.
