The DC-200/40-PZ-Si is a passive (undoped), large mode area, single mode core embedded in a high NA multimode fiber structure. This fiber is substantially similar to our DC-200/40-PZ-Yb active Yb-doped fiber, but with a pure silica core, and can be used to optimize procedures that will be used with the active version.
The inner cladding has a high numerical aperture (NA) due to the large index step between the air hole ring and silica. Microstructuring of the inner cladding allows a large mode field diameter while still maintaining a superior beam quality. The allsilica fiber sustains high power levels. It features a mode area of more than 700 µm2 while keeping single-mode beam quality. Moreover, the fiber is polarizing resulting in improved PER compared to normal polarization-maintaining fibers.
The fiber can also be used in applications requiring singlemode beam propagation in one direction and at the same time collection and propagation of scattered light or luminescence in the other direction for detection.
The fiber is available with sealed ends or with end-caps and high power SMA connectors.
