Abstract
An external cavity semiconductor laser system is disclosed wherein multiple segments of semiconductor material are excited with an array of pump sources. In one embodiment, a laser beam is reflected in a pattern to pass through multiple excited segments on a wafer of semiconductor material. In another embodiment, a series of wafers disposed in a laser cavity are excited. This pumping system spreads out the thermal load while providing a high power, high quality, laser beam.
