nLIGHT Corporation has released mode field tapers (MFTs) for efficient interconnection of dissimilar fibre geometries found in higher-power, diffraction-limited fibre lasers and amplifiers.
Using a proprietary process, nLIGHT is able to offer polarisation maintaining (PM) and non-PM MFTs with exceptionally low loss, high polaridation extinction ratio (PER), wide optical bandwidth and complete preservation of beam quality. nLIGHT’s MFTs accommodate pump coupling configurations with various input and output fibers, both single and double clad.
