SPATIAL OPTICAL PARAMETRIC COUPLING OF PICOSECOND probing of the phase transformation of a GaAs surface under femtosecond laser irradiation.

av M Shverdin — Pulses shorter than a few tens of picoseconds cannot be measured directly. A.V. Sokolov, D.R. Walker, D.D. Yavuz, G.Y. Yin, and S.E. Harris, Femtosecond.

The final point of discussion will be the use of pulse compression techniques to generate a 30 femtosecond optical pulse, the shortest optical pulse duration yet reported. Results: For femtosecond pulses, tissue separation was achieved best with pulse energies from 4 to 8 microJ and spot separations from 10-15 microns. Picosecond pulses accomplished less complete separations with pulse energies of 25 microJ and spot separations from 10 to 20 microns.

Picosecond Laser Material Processing Challenges in ultrafast precision laser Micro-machining of Metals at high repetition rates AndreAs TünnerMAnn andreas tuennermann received the diploma and ph.D. degrees in physics from the university of hannover in 1988 and 1992, respectively. In the begin- The aeroPULSE FS series builds on the picosecond platform by harnessing the company’s Optocage technology to provide femtosecond ultrafast-laser output at pulse durations shorter than 500 fs, with high pointing stability and output powers of 20 to 50 W. Green and UV frequency-conversion modules are available for the aeroPULSE platform, with single or multiwavelength options.

We have designed an ytterbium rod-type fiber laser oscillator with tunable pulse duration. This system that delivers more than 10 W of average power is self mode-locked. It yields femtosecond to picosecond laser pulses at a repetition rate of 74 MHz. The pulse duration is adjusted by changing the spectral width of a band pass filter that is inserted in the laser cavity. Using volume Bragg

For metals and materials behaving similarly (e.g. semiconductors with small gap compared to the photon energy), the pulse Convert Femtoseconds to Picoseconds (fs in ps). Femtoseconds and Picoseconds both are the units of TIME.

A femtosecond laser may provide quality improvement over a picosecond laser, but the higher laser cost is a serious consideration.

Absorption is about 1 femtosecond, relaxation takes about 1 picosecond, fluorescence takes about 1 nanosecond. S0 and S1 represent different electronic

Its symbol is fs. A femtosecond is equal to 1000 attoseconds, or 1/1000 picosecond. Because the next higher SI unit is 1000 times larger, times of 10 −14 and 10 −13 seconds are typically expressed as tens or hundreds of femtoseconds.
