| 摘要 |
The present invention relates to a device for outcoupling of light in an external cavity laser, which external cavity laser comprises at least one light emitting and/or amplifying element (300, 500, 600, 700, 800), at least one wavelength selective feedback element (340, 540, 640, 740, 840). The outcoupling device further comprises at least one polarization selective beam-splitting optical element (320, 520, 620, 720, 820), and at least one Faraday-rotator element (330, 530, 630, 730, 830).
