Laser diode array with an in-phase output

摘要

A laser diode array that includes a plurality of laser stripes each separated by an unpumped region. The array includes at least one first laser stripe and at least one second laser stripe. The first laser stripe emits a first laser beam. The second laser stripe emits a second laser beam. A phase shifter is connected to the stripes so that the phase of the second laser beam is shifted to be in phase with first laser beam. The resultant output beam of the array is a high power, high quality, diffraction limited beam.
