Abstract
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.

A laser diode array, comprising:
- at least one first laser stripe;
- at least one second laser stripe;
- and,
- a phase shifter connected to said second laser stripe(s).
A laser diode array, comprising:
- first laser means for generating a first laser beam that has a phase;
- second laser means for generating a second laser beam that has a phase;
- and,
- phase shifter means for shifting the phase of the second laser beam to be in phase with the first laser beam.
A method for operating a laser diode array, comprising:
- generating a first laser beam from a first laser stripe, the first laser beam having a phase;
- generating a second laser beam from a second laser stripe, the second laser beam having a phase;
- and,
- shifting the phase of the second laser beam to be in phase with the first laser beam.
