摘要
A semiconductor laser is disclosed whose front or rear surface is provided with a multilayer dielectric and/or reflective coating in such a way that either a temperature-independent differential quantum efficiency or a temperature-independent power output is obtained. The sequence of layers is chosen so that the reflection coefficient decreases with increasing light wavelength. (In other laser systems, it may be necessary for the reflection coefficient to increase).
