LARGE OPTICAL CAVITY LASER SOURCE IN LARGE FINESSE SPECTRAL RING

摘要

The present invention relates to a laser source, of the ring optical cavity type, and is characterized in that the cavity comprises a pumping gain optical fiber having a first end whose optical axis is optically aligned. with an output mirror, and whose second end is directed towards the first, its optical axis intersecting the optical axis of the first end on the end face of this first end while being distinct from the optical axis of the first end , a beam rephasing device and a non-reciprocal element being respectively disposed between the second and the first ends of the optical fiber. / P
