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 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 … 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).

Femtosecond pulse

It is composed of a sequence of prisms, or gratings. 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.

Although MLLs are capable of producing very high-peak power OFCs with femtosecond pulse durations, it is sometimes challenging to apply them directly for a

Only within two decades after the invention of the laser the duration of the shortest pulse shrunk by six orders of magnitude from the nanosecond regime to the femtosecond regime. Nowadays femtosecond pulses in … 2018-08-08 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. Precise control of the pulse’s width, duration, shape, repetition rate and propagation ensures that desired results are enhanced and unwanted effects are minimized. 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.

Amplified pulses are de-chirped to sub-160 fs duration in a grating compressor. This is the first 10 W-level source of femtosecond pulses with completely fibre-

Normally, femtosecond light pulses that cross at a nonzero angle overlap over only a small region in space. This limitation can be overcome by the use of diffraction orders of a grating. We investigate femtosecond pulse generation from a CW Laser diode by optical gating with a Mach-Zehnder electro-optic modulator.

Such lasers have been around since the 1970s in the form of so called dye lasers, the laser type used in the experiments where femtosecond pulses were ﬁrst produced [1].
