Abstract
A partially mirrored beam tap for use in wavelength and power monitoring, wherein the partially mirrored beam tap splits off at least two beams from an elliptical Gaussian output beam, wherein a first split-off beam is transmitted to an etalon and one or more first photo-detectors for wavelength monitoring, while a second split-off beam is transmitted to one or more second photo-detectors as a reference and for power monitoring. The partially mirrored beam tap splits off the first and second split-off beams from upper and lower tails of the output beam, wherein upper and lower portions of the partially mirrored beam tap comprise mirrored surfaces that reflect tails of the output beam and a center portion of the partially mirrored beam tap comprises a clear rectangular aperture that passes the output beam.
