Viscoelastic dynamics of nanoparticles optically trapped in moving fringe pattern in air-filled hollow-core fiber
Soumya Chakraborty, Gordon K. L. Wong, Philip St. J. Russell +1
We report optical trapping and transport of nanoparticles in a moving interference pattern in hollow-core photonic crystal fiber at atmospheric pressure, when competition between t…
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…
Shaping frequency correlations of ultrafast pulse-pumped modulational instability in gas-filled hollow-core PCF
Martin A. Finger, Nicolas Y. Joly, Philip St. J. Russell +1
We vary the time-frequency mode structure of ultrafast pulse-pumped modulational instability (MI) twin beams in an argon-filled hollow-core kagomé-style PCF by adjusting the pressu…
