We demonstrate Fourier synthesis of multiple coherent anti-Stokes Raman scattering signals in a single crystal of LiNbO 3 at room temperature. Isolated pulses with 25-fs duration and 640-780-nm wavelength range are generated without any active chirp compensator.
We demonstrated the generation of 34-muJ, 14-fs optical pulses with an ultrabroad bandwidth (540-1000 nm) by the use of one angularly-dispersed non-collinear optical parametric amplifier.

We report experiments demonstrating enhanced coupling efficiencies of high-contrast laser irradiation to nanofabricated conical targets. Peak temperatures near 200 eV are observed with modest laser energy (10 J), revealing similar hot-electron localization and material heating to reduced mass targets (RMTs), despite having a significantly larger mass. Collisional particle-in-cell simulations attribute the enhancement to self-generated resistive (∼10 MG) magnetic fields forming within the curvature of the cone wall, which confine energetic electrons to heat a reduced volume at the tip. This represents a different electron confinement mechanism (magnetic, as opposed to electrostatic sheath confinement in RMTs) controllable by target shape.
