Hollow fiber delivery of Q-switched, multiple-order Nd: YAG laser light

摘要

We proposed a use of hollow fibers for delivery of harmonic pulses of high-peak power, Nd:YAG laser light Hollow fibers with an internal silver and polymer layer were fabricated by a liquid phase conating technique and, in an experiment using the 2nd-orde Nd:YAG laser, it was shown that the fiber has low-loss property because of the smooth inner surface and proper coating materials. High-power capability of the fiber is also shown when the hollow core is purged with helium gas.
