Spatio-temporal measurement of ionization-induced modal index changes in gas-filled PCF by prism-assisted side-coupling
Barbara M. Trabold, Mallika I. Suresh, Johannes R. Koehler +3
We report the use of prism-assisted side-coupling to investigate the spatio-temporal dynamics of photoionization in an Ar-filled hollow-core photonic crystal fiber. By launching fo…

Pump-probe study of plasma dynamics in gas-filled photonic crystal fiber using counter-propagating solitons
Mallika I. Suresh, Felix Köttig, Johannes R. Koehler +2
We present a pump-probe technique for monitoring ultrafast polarizability changes. In particular, we use it to measure the plasma density created at the temporal focus of a self-co…
