Compression of high-energy ultrashort laser pulses through an argon-filled tapered planar waveguide
Abstract : We propose a hollow tapered planar waveguide for compression of high-energy ultrashort laser pulses. Direct measurements suggest that it seems to find a very good trade-off among the energy throughput, the beam focusability, and the pulse compressibility. With a Ti:sapphire laser pulse of 12.0 mJ and 40 fs , our experiment produces an output pulse of 9.4 fs duration with energy 9.1 mJ (transverse magnetic mode) or 10.0 mJ (transverse electric mode) in argon, each exhibiting a nice spatial mode. To evaluate such a tapered waveguide, the linear wave propagation theory and the solution to its complex propagation constant are also presented.
