Self-imaging combiners can achieve near-perfect filled-aperture coherent beam
combination in an all-fiber format with a high-power operation capability. In this Letter, the …

The self-imaging effect in a square core fiber has been investigated, and an integrated all-
fiber combiner has been proposed based on a large mode area double clad fiber, which can …

All-fiber coherent beam combiners based on the self-imaging effect can achieve a near-
perfect single laser beam, which can provide a promising way to overcome the power …

We present a new approach for an all-fiber coherent beam combining by active phasing a
fiber combiner. The combined advantages of all-fiber format and large output core of the …

We demonstrate an all-fiber 7× 1 signal combiner with an output core diameter of 50 μm for
high power incoherent beam combining of seven self-made Yb-doped single-mode fiber …

A 3 kilowatt level incoherently combined beam with 98% measured power transfer efficiency
is demonstrated using an all-fiber Y-branch combiner. An M 2 factor of≤ 3.5 was measured …

Beam combining is one of the most potential methods to break through the output power
limitations of a single fiber laser. In this letter, we report a high-power experimental result …

Coherent beam combining (CBC) is a promising technique to realize high-brightness laser
output. As a key point to implement CBC, an appropriate phase control feedback structure …

We show the feasibility of producing a low-mode all-fiber combiner fabricated from a large
core and extremely small NA fibers. Although these fibers support multiple modes, the …

Coherent beam combining of fiber lasers has the capability of scaling to unprecedented
power with near-diffractive-limitation beam quality. Aperture technology is the key factor of …
