We demonstrate remote elemental analysis at distances up to 90 m, using a laser-induced breakdown spectroscopy scheme based on filamentation induced by the nonlinear propagation of unfocused ultrashort laser pulses. A detailed signal analysis suggests that this technique, remote filament-induced breakdown spectroscopy, can be extended up to the kilometer range.

    Distortions of ultrashort laser pulses propagating through turbulence are investigated both experimentally and numerically. As expected, a strong correlation is found between temporal distortions and local intensity on the speckle pattern. We suggest that the localization of distortions in...

    Chirped ultrashort light pulses offer new options for coherent nonlinear spectroscopy and microscopy. We show here that the temporal resolution of spectroscopy and microscopy based on coherent anti-Stokes Raman scattering (CARS) can be smoothly tuned within a broad range, with upper and lower...

    We have investigated high-frequency ultrasound generated by single laser pulses in thin (50 μm) aluminum foils as a function of the laser fluence. Laser-pulse durations of 80 fs and 270 ps were used to compare the ultrasound generated in two very different regimes: thermoelastic and ablation....

    We report a diode-pumped picosecond Nd:GdVO4 regenerative amplifier system designed for micro-machining applications. Nd:GdVO4 was chosen as gain material because it offers – in comparison to the commonly used Nd:YVO4 – improved thermal properties and a larger gain bandwidth. At...

    We have developed a beam stabilization system for high-power femtosecond lasers operating at a repetition rate of 1 kHz. The beam pointing at a hollow fiber input was stabilized to within 1 μm rms and the fluctuations of the broadened spectra and power were significantly improved. This...
