Phys Rev A. 2010 Jan;1001. doi: 10.1103/PhysRevA.81.033840.

We analyze optical soliton propagation in the presence of weak absorption lines with much narrower linewidths as compared to the soliton spectrum width using the novel perturbation analysis technique based on an integral representation in the spectral domain. The...

The Thomson deflectometer: a novel use of the Thomson spectrometer as a transient field and plasma diagnostic.

The Review of scientific instruments

Ter-Avetisyan S, Schnürer M, Nickles PV, Sokollik T, Risse E, Kalashnikov M, Sandner W, Priebe G.
PMID: 18377003
Rev Sci Instrum. 2008 Mar;79(3):033303. doi: 10.1063/1.2901579.

Laser accelerated proton beams have been used for field characterization in expanding plasmas. The Thomson parabola spectrometer, as a charged particles analyzer, also allows precise measurement of the charged particles' trajectories. The proton's deflections by fast changing plasma fields...

High-power 200 fs Kerr-lens mode-locked Yb:YAG thin-disk oscillator.

Optics letters

Pronin O, Brons J, Grasse C, Pervak V, Boehm G, Amann MC, Kalashnikov VL, Apolonski A, Krausz F.
