Abstract

Semiconductor laser diodes continue to advance in the field of high power lasers. Output powers of monolithic sources have been demonstrated in excess of 120 W cw, while stacked arrays of diodes have exceeded 400 kWatts peak output power. Several areas of advancement have been dramatically impacted by the technologies over the past 3 years including wavelength access of, single mode coherent operation of, and high reliability operation of laser diodes.
