Abstract
A new and improved flip chip combination of a laser diode chip and a carrier chip with built-in thermoelectric cooler. This invention comprises an array of laser stripes, each having a separate cooling strip bonded to it. Each cooling strip could be controlled either separately or by a common source, permitting cooling of each laser stripe at a different rate or at the same rate respectively, to thereby maintain the laser stripes at the same or different operating temperatures.
