Femtosecond laser-assisted astigmatic keratotomy has been primarily described for treatment of high astigmatism following penetrating keratoplasty. 8,9 As the femtosecond laser is capable of creating incisions with high precision and reproducibility, it can be used to control the desired length, shape, and depth of incisions for astigmatic keratotomy.

By using Extreme UV light from a high harmonic generation source (HHG), we are able to study the element specific magnetization dynamics in femtosecond 

Femtochemistry enables us to understand why certain chemical reactions take place but not others. In my pursuit of nonlinear optics it became obvious that if I was serious about learning about high power lasers and the cool things you can do with them, I Femtosecond laser-assisted astigmatic keratotomy has been primarily described for treatment of high astigmatism following penetrating keratoplasty. 8,9 As the femtosecond laser is capable of creating incisions with high precision and reproducibility, it can be used to control the desired length, shape, and depth of incisions for astigmatic keratotomy. 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. For context, a femtosecond is to a second as a second is to about 31.71 million years; a ray of light travels approximately 0.3 μm ( Femtosecond to Second Studies of a Water-Soluble Porphyrin Derivative in Chemical and Biological Nanocavities By Yilun Wang (640871), Boiko Cohen (1374567), Laszlo Jicsinszky (1448296) and Abderrazzak Douhal (1374573) The femtosecond-to-second photochemistry of red-shifted fast-closing anion channelrhodopsin PsACR1† Yusaku Hontani , a Matthias Broser , b Arita Silapetere , b Benjamin S.

Kennis * a ‘A femtosecond is to one second in duration what one second is to 30 million years.’ ‘In other words, what could you do with a femtosecond x-ray source?’ ‘If you want to study this motion, you need femtosecond pulses of light.’ ‘The other theory contends this conversion takes much longer, about 500 femtoseconds.’ 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.
