Abstract:
1. A laser diode device comprising: a housing having a mounting area in a cavity of the housing, at least one laser diode chip that emits electromagnetic radiation through a radiation exit area during operation, at least one covering element which is transmissive, at least in places, to the electromagnetic radiation generated by the laser diode chip during operation, and a deflection element, that directs at least part of the electromagnetic radiation generated by the laser diode chip during operation in a direction of the covering element, wherein the radiation exit area of the laser diode chip runs substantially transversely or substantially perpendicularly with respect to the mounting area and/or with respect to the covering element, the covering element connects to the housing and tightly closes the housing such that a leakage rate is at most 5*10^(−8) (Pa*m^3)/s.
