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…
Efficient single-cycle pulse compression of an ytterbium fiber laser at 10 MHz repetition rate
F. Köttig, D. Schade, J. R. Koehler +2
Over the past years, ultrafast lasers with average powers in the 100 W range have become a mature technology, with a multitude of applications in science and technology. Nonlinear…
Coherent control of flexural vibrations in dual-nanoweb fibers using phase-modulated two-frequency light
Johannes R. Koehler, Roman E. Noskov, Andrey A. Sukhorukov +2
Coherent control of the resonant response in spatially extended optomechanical structures is complicated by the fact that the optical drive is affected by the back-action from the…
