Abstract:
1. An integrated laser light emission system, comprising: a laser gain medium having at least one surface including an exposed region; and a plurality of vertical-cavity surface-emitting laser diode arrays, each said laser diode array having a mount for mounting said respective laser diode array to the at least one surface of the laser gain medium and aligned with a respective said exposed region, wherein no intervening lens elements are contained between light sources of the vertical-cavity surface-emitting laser diode arrays and the laser gain medium, and wherein an area of the exposed surface of the laser gain medium is greater than the cross section dimension of the light beam emitted by each respective vertical-cavity surface-emitting laser diode array, wherein said mount mounts the vertical-cavity surface-emitting laser diode arrays in a junction-down position to the laser gain medium such that electrodes of respective vertical-cavity surface-emitting laser diodes face a surface of the laser gain medium, wherein said mount elevates the electrodes of respective vertical-cavity surface-emitting laser diode arrays over the laser gain medium providing a gap between the respective vertical-cavity surface-emitting laser diode array and laser gain medium sufficient for coolant to flow, and wherein low-loss diffuser plates seal the electrodes and the surface of each respective vertical-cavity surface-emitting laser diode array having the electrodes in order to protect the surface of each laser diode array from exposure to coolant.
