Abstract:
It is an object of the invention to simplify the power stabilization of laser diodes. For this purpose, a laser device comprising a die and thereon a first laser diode and a second laser diode is provided. The second laser diode has a structure or element that avoids lasing if a supply voltage is applied that is sufficient for the first semiconductor laser cavity to emit laser light.
