Abstract
The present invention provides for an improved package for a laser diode. The package has portions of its inner surfaces covered with a non-reflecting material, such as simple black paint, non-reflective metals or specific anti-reflection coatings. Such non-reflecting materials surprisingly enhances the performance of packaged laser diodes used as pumping lasers for fiber amplifiers, for example.
