Abstract:
A laser diode assembly, comprising:a first enclosure including:a base plate formed of a material that is thermally and electrically conductive and has a first coefficient of thermal expansion and a thermal conductivity that is greater than about 100 W/m.multidot.K,a side wall band formed of a material that is electrically conductive and has a thermal conductivity of less than about 100 W/m.multidot.K and has a second coefficient of thermal expansion that is within .+-.30% of the first coefficient of thermal expansion, the sidewall band having a lower edge attached to the base plate by a metallurgical bond, the sidewall band having a optical port formed therein, anda lid attached to an upper edge of the sidewall band, wherein the base plate and the side wall band and the lid define a sealed volume therein; anda laser diode disposed inside the sealed volume for producing an optical output that exits the sealed volume through the optical port.
