2103807 9214287 PCTABS00014 An external cavity semiconductor laser system (100) is disclosed wherein multiple segments of semiconductor material are excited with an array of pump sources (20). In one embodiment, a laser beam is reflected in a pattern to pass through multiple excited segments on a wafer of semiconductor material (12). On 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.
