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

A loosely- focused femtosecond pulse changes its color as it propagates through a transparent material, producing a pulse of white light. This continuum generation is one of the most dramatic examples of the extraordinary difference between the interaction of normal light and of powerful laser pulses with transparent materials.

Figure 2 shows the result of irradiating single femtosecond laser pulses with an energy of 0.23 µJ on the spin valve sample with x = 33%. We first initialize the sample in a P+ configuration using an external magnetic field. After the first pulse, a light‐red color appears, corresponding to the reversal of the Co/Pt multilayer's magnetization. 210 Femtosecond Pulse Shaping tor Molecular Control . For the reflectron and other examples which have been investigated, the target operator is simply a projection operator onto a target wave function which we have chosen to be a minimum uncertainty Gaussian centered at a particular tra of femtosecond pulses.

The femtosecond pulse generation has been obtained in laser oscillators based on solid-state laser media with a very large fluorescence band-width in the range of ten-hundred nanometers.

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.

A femtosecond Cr:ZnS master oscillator emitting 40 fs pulses at 2.4 µm seeds both a Ho:YLF regenerative amplifier and a two-stage OPCPA based on ZnGeP2 crystals. The 2.05 µm few-picosecond pump pulses from the Ho:YLF amplifier have an energy of 13.4 mJ.

In this case, hundreds of thousands and even more longitudinal modes of oscillation are phase-locked.

Different kinds of pulse shapes may be required, depending on the application. Normally, femtosecond light pulses that cross at a nonzero angle overlap over only a small region in space.

10 May 2012 Femtosecond-pulse surface-emitting semiconductor lasers with agile repetition frequencies have the potential to be used as flexible frequency 

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. niques, femtosecond pulse shaping is poised to impact many diverse and additional applications. In the terminology of electronic instrumentation, femtosecond lasers constitute the world’s best pulse generators, while pulse shaping is the short pulse optical analog to electronic function generators, which widely provide electronic square waves, triangle 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.
