✦ Synopsis

Laser ignition via hollow core photonic crystal fiber (PCF) as a delivery medium has been demonstrated in the present work. Minimum pulse energy from a Q-switched Nd:YAG laser of only 150 μJ was achieved to ignite rich fuel mixtures of methane-air. Aspheric lens of high numerical aperture has been used to focus the laser beam. Different air/fuel ratios have been examined with different gas temperatures. The results indicate the feasibility of using hollow core PCF for high power beam transmission for laser ignition applications.

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
