14.6 APPLICATIONS
The diversity of new or improved features, beyond conventional fibers, means that
PCFs are finding an increasing number of applications in ever y widening area of
science and technology.
14.6.1 High Power and Energy Transmission
Larger mode areas allow higher power to be carried before the onset of intensity-
related nonlinearities or damage, with obvious benefits for delivery of high laser
power, and for high-power fiber amplifiers and lasers. ESM-PCF’s ability to
remain sing le mode at all wavelength s where it guides, and for all scales of
structure, means that the core area can be increased without the penalty of
introducing higher ...
