There is still significant need for power scaling of fiber lasers. Large-mode-area fibers are a key for the mitigation of optical nonlinearities. In recent years, mode instability has shown itself to be an additional significant limiting factor for single-mode power scaling in the regime of a few hundred watts to kilowatts. It is better appreciated now that further power scaling requires significant...
We have demonstrated ytterbium-doped fiber lasers in 50µm-core photonic bandgap fibers with robust single mode output, a record core diameter for active photonic bandgap fibers, with slope efficiency exceeding 70%.
We present a design and manufacture of a web-structured all-solid photonic bandgap fiber. We show experimentally that the loss can be reduced to a practical level (∼7 dB/km) with an appropriate design of the web structure.
The structural dependence of factors which mainly affect a bending loss property is theoretically investigated in all-solid photonic bandgap fibers. A design principle for realizing a low bending loss is successfully figured out.
We propose a novel concept of cladding structure in all-solid photonic bandgap fibers. It promises low bending and confinement losses with single-mode operation. The mechanism is based on the new concept of heterostructured cladding.
