2018-08-08 · Femtosecond semiconductor lasers are ideal devices to provide the ultrashort pulses for industrial and biomedical use because of their robustness, stability, compactness and potential low cost. In A femtosecond laser is a laser which emits optical pulses with a duration well below 1 ps (→ ultrashort pulses ), i.e., in the domain of femtoseconds (1 fs = 10 −15 s). It thus also belongs to the category of ultrafast lasers or ultrashort pulse lasers (which also include picosecond lasers ). At that time, the French Ministry of Education decided that, in view of the growing importance of ultrashort laser pulses for the national scienti?c community, a Femtosecond Centre should be created in France and devoted to the further education of scientists who use femtosecond pulses as a research tool and who are not specialists in lasers or even in optics. for measuring jitter between two femtosecond light pulses was developed using a Ti:Sa laser and self-phase modulation in glass which simulated the conditions of the Tesla test facility (TTF) at Desy, Hamburg.

The temporal delayed orthogonal pulse pairs generated by the phase shaping technique are used to study the coherent control of the rotational wave packet dynamics in air. 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

In optics, femtosecond pulse shaping refers to manipulations with temporal profile of an ultrashort laser pulse. Pulse shaping can be used to shorten/elongate the duration of optical pulse, or to generate complex pulses. 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.

Picosecond and femtosecond pulse generation in a regeneratively mode-locked Ti:sapphire laser. Abstract: The authors have produced transform-limited pulses 

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. After parametric amplification in one or more amplifier stages with nonlinear crystals, high energy signal pulses are temporally recompressed to get high power femtosecond laser pulses. 2000-05-02 · We review the field of femtosecond pulse shaping, in which Fourier synthesis methods are used to generate nearly arbitrarily shaped ultrafast optical wave forms according to user specification.

tral amplitudes and phases of aspectrally dispersed ultrafast pulse that are very effective for femtosecond pulse shaping (Weiner and Heritage, 1987). The output pulse of such a Fourier-plane filter is given by computing the inverse Fourier transform of the input pulse multiplied by the complex filter transmittance.

We investigate femtosecond pulse generation from a CW Laser diode by optical gating with a Mach-Zehnder electro-optic modulator. 45 ps pulses are amplified to ten’s of watt peak power and propagated through a standard polarization maintaining fiber to reach enough spectral broadening by self-phase-modulation. The femtosecond pulse compressor should be placed in the beam path between the laser and the microscope. Two beam heights are supported: 4.75" (120.7 mm), for Thorlabs' Tiberius laser and Coherent's Chameleon™ lasers, and 4.25" (108.0 mm), for other common commercial lasers. The beam height is set by a base plate that is included with the unit.
