Vertical Cavity Surface Emitting Lasers [PDF]
MRS Bulletin, 2002 The goal of this project was to increase the power of vertical cavity surface emitting lasers and to convert their wavelength into the blue/ultraviolet and the infrared for sensing applications. We have increased the power to the multi-watt level and have generated several milliwatts of blue light using optical pumping.
