Junji Sone, Katsumi Yamada, Akihisa Asami, Jun Chen 2014, 'Sub-Micrometer Size … The featured FemtoSecond Grating (FSG ®) is a uniform apodized grating fabricated with ultra-short laser pulses, using a special through-the-coating inscription technique.The inscribed FSG ® maintains the pristine high strength of the optical fiber and adds new performance features. The FSG-Axx is a uniform apodized grating written into a high-strength optical fiber, optimized for operation Femtosecond laser microfabrication shows many advantages, such as precision, short time, and environmental friendliness, over traditional fabrication methods. 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 2021-4-23 · Femtosecond laser research led to the development, in 2000, of a system that revolutionized the measurement of optical frequencies and enabled optical clocks. Continuing the progress, today’s top-shelf technologies are beginning to make it possible to observe events that last less than 100 attoseconds, or quintillionths of a second.
It also can be expressed as 1,000 picoseconds or 1,000,000 nanoseconds. 1 Oct 2015 These lasers produce ultra-short pulses—less than 400 femtoseconds—that leave no thermal fingerprint on the part. A femtosecond is 10-15

ORIGAMI IRO is a widely tunable (210 nm to 11 µm), cost-effective femtosecond laser and optical parametric amplifier system with multi-µJ output. Get industry-leading beam pointing stability in a compact air-cooled system that is fully automated and environmentally stable. A femtosecond is the SI unit of time equal to 10-15 or 1 ⁄ 1 000 000 000 000 000 of a second; that is, one quadrillionth, or one millionth of one billionth, of a second. Zewail, who would go on to win a Nobel Prize for his research, measured these miniscule changes in femtoseconds; a femtosecond is one millionth of a billionth of a second. A femtosecond is one billionth of one millionth, or one quadrillionth of a second.It can be written as 10-15 second.Even shorter than this is an attosecond.. 200 femtoseconds - the fastest chemical reactions Femtosecond laser research led to the development, in 2000, of a system that revolutionized the measurement of optical frequencies and enabled optical clocks. Continuing the progress, today’s top-shelf technologies are beginning to make it possible to observe events that last less than 100 attoseconds, or quintillionths of a second.
