ABSTRACT:
A surface-emitting extended cavity laser with intracavity frequency conversion is provided with at least one surface-emitting laser element with multiple layers to obtain laser light at a fundamental frequency, reflector means, spaced from the laser element to form an external cavity, a frequency conversion device, arranged within the external cavity to generate light at a second frequency and tunable optical band-pass filter means, arranged within the external cavity and detector means, where said optical band-pass filter means are tunable upon a signal, which is obtained by the detector means to enable a frequency control at the fundamental frequency.
