Abstract: The invention relates to a method for regulating the average wavelength of a laser, especially a semiconductor laser, comprising a wavelength-selective, at least partially reflecting optical element (27) and being operated in a unimodal manner.

Abstract: The invention relates to an optoelectronic emission module comprising a housing (B), which has electrical terminal contacts (5) for supplying and/or carrying away electric signals or for supplying electrical power. Said emission module also has at least one optical emission element (13), which is arranged inside the housing (3), and has at least one optical waveguide (17), which is held inside or on the housing (3) and in whose injection end (19) the light emitted by the at least one optical emission element (13) can be injected. The at least one optical emission element (13) and the injection end (19) of the at least one optical waveguide (17) are mounted on a supporting element. The invention also relates to a method for producing an emission module of the aforementioned type.
