✦ Synopsis
We report the delivery of high-energy nanosecond pulses (10 ns pulse width) from a Q-switched Nd:YAG laser through the fundamental mode of a hollow-core photonic crystal fiber at 1064 nm. At a pressure of 450 mbar, energies greater than 1 mJ were delivered in a single spatial mode through the hollow-core fiber, coupling efficiencies over 80% were demonstrated.
