Input pulse duration from 5 fs. Spectral phase interferometry for direct electric- field reconstruction (SPIDER) is one technique that can recover the spectral phase of an input pulse, without needing any reference pulse. SPIDER interferes two pulses which are separated in time and in frequency, and the resultant interferogram is read by a spectrometer. Lastek is the exclusive distributor in Australia and New Zealand for more than fifty leading international laser, optic, detection, spectroscopy and imaging manufacturers. Figure 1: Spectrum of two femtosecond pulses, where one pulse is nonlinearly chirped and delayed by 600 fs. The spectral modulation can be used to reconstruct the spectral phase of the chirped pulse. A high sensitivity can be achieved, as such a heterodyne method works well even if the signal pulse energy is much lower than that of the reference pulse.

How short? Each pulse lasts only a few femtoseconds. (A femtosecond is 0.000000000000001 second. femtosecond laser pulses possible SPIDER Spectral Phase Interferometry for Direct Electric-ﬁeld Reconstruction FROG Frequency Resolved Optical Gating GRENOUILLE GRating-Eliminated No-nonsense Observation of Ultrafast Incident Laser Light E-ﬁelds Oral Presentation for AP304 – p.8 2018-12-20 · An asymmetric \\b{eta}-sheet structure of spider silk is said to induce optical second harmonic generation.

An asymmetric β‐sheet structure of spider silk is said to induce optical second harmonic generation. In this paper, using an in‐house nonscanning type femtosecond pulse laser second harmonic generation microscope, we characterized the behavior of the β‐sheet of spider silk under an applied external force.

Photodissociation is a chemical reaction in which a chemical compound is broken down by photons. It is defined as the interaction of one or more photons with one target molecule. VICTUS Femtosecond Laser Platform - Full Vision & Versatility. With thirty years of experience in the ophthalmic laser surgery field, the 3rd Generation VICTUS Femtosecond Laser Platform combines our expertise in surgeon and patient needs with German engineering and intuitive design. Femtosecond pulse-measurement methods have helped ultrashort pulses to achieve a wide range of applications and to enter even shorter temporal regimes.

struction (SPIDER): the use of a femtosecond pulse shaper eliminates the need for an interferometer setup, allows dispersion-free SPIDER operation and at the same time compression even of complex pulses. Beyond compression, the scheme allows precise phase control at the site of the microscopic experiment. We present the
