Now this has been applied in structuring Janus membranes by researchers. This review covers recent advances in femtosecond laser-structured Janus membranes with asymmetric surface Femtosecond laser pulses (pump) excite the oxygen vacancy (O-V)–contained metal oxides. Interaction of broadband supercontinuum pulses (probe) with the excited states characteristic of the oxygen vacancies induces a spectroscopic picture of TA as a function of photon energy (hν) and time delay (τ). , Femtosecond x-ray spectroscopy of an electrocyclic ring-opening reaction.

For industry, femtosecond lasers are suitable for ultra-fine processing of materials with little or no heat affected zone (HAZ). Target materials for these lasers include glass, OLED, IC packages/wafers, and flexible thin films.
Low-divergence femtosecond X-ray pulses from a passive
Femtosecond laser microprocessing is a direct, maskless technique capable of inducing a permanent refractive index increase buried beneath the surface of transparent glasses and polymers, enabling photonic circuit fabrication in 3D geometries. 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 ). Our Femtosecond Autocorrelator and Femtosecond Pulse Compressor are recommended for use with our Ti:sapphire lasers.
Femtoseconds – Termwiki, millions of terms defined by people
In one femtosecond, light travels just 300 nanometers — about the size of the biggest particle that can pass through a HEPA filter, and just slightly larger than the smallest bacteria. Another way of thinking about the length of a femtosecond is this: One femtosecond is to one second as one second is to about 32 million years. The femtosecond laser was introduced in the U.S. in the early 1990s and developed by Dr. Kurtz at the University of Michigan. It was approved in 2001 by the U.S. Food and Drug Administration for use in laser-assisted in situ keratomileusis, or LASIK eye surgery. In LASIK, the femtosecond laser is used on the cornea to create a corneal flap.
