While the broad spectral width of the femtosecond Beginning with mode-locking of glass lasers in the 1960s, the development of dye lasers brought the pulse width down from picoseconds to femtoseconds. Beginning with mode-locking of glass lasers in the 1960s, the development of dye lasers brought the pulse width down from picoseconds to femtoseconds. Their time structure, providing X-ray pulses of a few tens of femtoseconds in duration protein structural dynamics on the femtosecond to picosecond time-scale, Tunable, continuous-wave Ti: sapphire channel waveguide lasers written by femtosecond and picosecond laser pulses.

Femtosecond to picosecond

The FemtoFiber smart 780 is the ideal choice for integration 1998-09-14 · In contrast, for femtosecond plasma volumes of approximately 5 to 10 pm at threshold energies, cavitation sizes are predicted at approximately half picosecond values, approximately 12 pm.14 This Femtosecond laser pulses are much harder to measure than picosecond or nanosecond pulses. Nanosecond pulses can be easily measured using a fast photodiode and an oscilloscope. The fast photodetector produces a pulse of current that mimics the optical pulse, and an oscilloscope capable of reproducing the pulse traces it on a screen. are sensitive to the femtosecond-scale intramolecular dy-namics (i.e., bond vibrations), gigahertz-to-terahertz regime is sensitive to its picosecond-scale intermolecular dynamics a)Author to whom correspondence should be addressed. Electronic mail: vinh@vt.edu (i.e., molecular motions involving hydrogen bond break-ing).

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. The NKT Photonics ultrafast lasers offer a wide range of pulse lengths from femtosecond to picosecond and output power up to 50 W. Get variable or fixed repetition rate, single shot or burst mode, and optimize for your application.

using femtosecond to picosecond electron or proton pulses as probes. However, poor spatial resolution poses great challenges to simulta-neously recording both the global and local field features. Here, we present a direct 3D measurement of a transient electric field by time-resolved electron schlieren radiography with simultaneous

Example: convert 71 s to ps: 71 s = 7.1E-11 ps However, in general, polymers deteriorate rapidly owing to laser‐induced heating effects. In this study, we investigate the optimum irradiation conditions for PLLA processing, using an ultrafast laser and finely controlling the pulse duration over the femtosecond‐to‐picosecond range. Picosecond and Femtosecond OPOs. Because light travels a distance of only 300 μm in 1 ps, it is generally not possible for the down-converted light to traverse the nonlinear medium many times, and thereby buildup from noise, within the time duration of a single picosecond pulse.

Picosecond and femtosecond pulsed lasers are available in infrared up to 10 W at 1.5 μ m, up to 100 W at 1.06 μ m or as a second harmonic source up to 5 W at 0.52 μ m. Femto pulse lasers range from 400 to 600 fs, pico pulse models range from 10 ps to 1 ns. For some models the pulse duration can be adjusted by the user.

Its symbol is fs.
