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…

Long-lived refractive index changes induced by femtosecond ionization in gas-filled single-ring photonic crystal fibers
Johannes R. Koehler, Felix Köttig, Barbara M. Trabold +2
We investigate refractive index changes caused by femtosecond photoionization in a gas-filled hollow-core photonic crystal fiber. Using spatially-resolved interferometric side-prob…
