Buying Large Mode Area Fibers
Optical fibers with particularly large mode areas are useful for high-power fiber amplifiers and lasers, as they have reduced nonlinear effects. These fibers allow for the efficient transmission of high-power laser light with minimal distortion.

 Solutions for Innovators NKT PhotonicsBregnerødvej 144 3460 Birkerød Denmark See us at SPIE Photonics West 2025 in San Francisco, January 25–30 (booth 3401)! |  Our large mode area photonic crystal fibers are designed for diffraction-limited high-power delivery. The large mode area prevents nonlinear effects and material damage. With standard fibers, you trade large mode areas for single-mode operation. With our large mode area fibers, you get single-mode operation in a wide range of wavelengths. Also available in a polarization-maintaining version. |
