In a laser diode arrangement for generating single mode tunable laser radiation wherein the laser diode forms a first resonator and has rear and front facets and a second external resonator is coupled to the first resonator, and wherein an optical transmission component and a wavelength selective optical reflection element are arranged in the laser light path from the laser diode for directing laser light into the external resonator and coupling it back into the first resonator, means are provided for uncoupling the laser radiation from the first resonator by way of the rear facet of the laser diode, the rear facet and the optical reflection element having a reflectivity ratio of less than 1.
