The beam height is set by a base plate that is included with the unit. Our Femtosecond Autocorrelator and Femtosecond Pulse Compressor are recommended for use with our Ti:sapphire lasers. Our supercontinuum generation kit spectrally broadens fs pulses near 800 nm. We also offer ultrafast optics, a dispersion measurement system, optical delay lines, and dispersion-compensating fiber. Femtosecond pulse laser for space operation. In our investigation, a fibre femtosecond laser was operated in space as an attempt ever made for the first time to our knowledge. Short pulses deliver high peak intensity with relatively low pulse energy, making femtosecond pulses the ideal choice for imaging living tissue while limiting potential damage.

Femtosecond pulse

When properly adjusted it can alter the spectral phase φ(ω) of the input pulse so that the output pulse is a bandwidth-limited pulse with the shortest possible duration. The frequency comb of mode-locked femtosecond pulse lasers has led to remarkable advances in many fields; high resolution spectroscopy 4, 5, broad band calibration of astronomical spectrographs 6, Femtosecond laser pulses are used for the ablation of metals and dielectrics (2D and 3D structures), structural changes of materials, optical changes or mechanical processing such as cutting, drilling or milling in order to replace mechanical machining tools. From: Laser Growth and Processing of Photonic Devices, 2012 Femtosecond laser pulse delivered by fiber cable The FD Series is uniquely designed to deliver femtosecond laser pulses via an optical fiber cable to the user application. Introduced primarily for imaging proteins, the FD laser can serve many other applications where a handy delivery of fs pulses are required.

By continuously changing the intrapulse delay of the pump pulse, we measured the corresponding revival signals and obtained a two-dimensional rotational coherent spectrum (2D RCS). An additive property of the rotational This paper describes techniques for high-energy laser pulse amplification in multi-PW femtosecond laser pulses.

For gas-phase UED experiments, the laser beam is focused to a spot size below 0.5 mm to achieve high fluence and minimize the group velocity mismatch.

Femtosecond pulses from the amplifier were focused using a 20 cm lens onto a one mm quartz cuvette. The cuvette contains a liquid sample for Z-scan experiments, where the path length of the sample cell satisfies the condition that the cell-length is less than the Rayleigh range of the focusing lens. Femtosecond synchrotron pulses were generated directly from an electron storage ring. An ultrashort laser pulse was used to modulate the energy of electrons within a 100-femtosecond slice of the stored 30-picosecond electron bunch. The energy-modulated electrons were spatially separated from the long bunch and used to generate ∼300-femtosecond synchrotron pulses at a bend-magnet beamline Broad bandwidth femtosecond oscillator pulses are temporally stretched up to a signal pulse duration comparable to the pump pulse duration, usually in the range of picoseconds or nanoseconds.
