Transient Gas-Dynamics Filamentation of High-PowerFemtosecond Laser Pulse in Compressed Argon

A.M. Kabanov, E.E. Khoroshaeva, P.V. Babushkin, V.K. Oshlakov, Yu.E. Geints

Pressure shock drops in compressed argon trigger early multiple filamentation and broaden femtosecond laser spectra by up to 80 nm in proportion to initial pressure.

The bundle contains the canonical record plus signed events. A mirror can host it anywhere and recompute the same current state with the deterministic merge algorithm.

Claims

C1strongest claim

The magnitude of this spectrum broadening can reach 80 nm and is proportional to the initial gas pressure.

C2weakest assumption

That the observed early onset of multiple filamentation and spectrum broadening are directly caused by the jet flows and vortex gas turbulence induced by the pressure shock-drop, rather than other factors such as changes in gas density or ionization.

C3one line summary

Pressure-drop-induced turbulence in compressed argon triggers early multiple filamentation of femtosecond pulses and broadens their spectrum proportionally to initial gas pressure.
