Electrophysiological Characterization of GFP-Expressing Cell

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. And femtosecond lasers are now the most stable light sources ever developed.

The spectral phases and amplitudes of the transform-limited pulse, the linear chirped pulse, the cubic dispersion pulse, the quartic dispersion pulse, the self-phase modulation pulse and the pulses with the Abstract. 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.

Asymmetric β-sheet protein structures in spider silk should induce nonlinear optical interaction such as second harmonic generation (SHG) which is experimentally observed for a radial line and dragline spider silk by using an imaging femtosecond laser SHG microscope. 2017-01-01 The Compact LX Spider by APE is a portable, compact and robust instrument for spectral and temporal characterization of femtosecond laser pulses. It is the ideal candidate for Ti:Sa laser applications and other ultrashort pulse oscillators or amplifiers in the wavelength range 750 – 900 nm. The technique, spectral phase interferometry for direct electric-field reconstruction (SPIDER), measures the interference between a pair of spectrally sheared replicas of the input pulse. Direct (noniterative) inversion of the interferogram yields the electric field of the input pulse without ambiguity. LX Spider is a highly compact instrument for the characterization of femtosecond laser pulses in the range of 16 … 200 fs. Spider IR is the best choice for pulses between 30 and 500 fs at 1 µm central wavelength.

Spider femtosecond

SPIDER interferes two pulses which are separated in time and in frequency, and the resultant interferogram is read by a spectrometer. A thin etalon is used to pick off a portion of the input pulse and split it into two pulses delayed Femtosecond up-conversion is a pump-probe technique that uses nonlinear optics to combine the fluorescence signal and probe signal to create a signal with a new frequency via photon upconversion, which is subsequently detected. The probe scans through delay times after the pump excites the sample, generating a plot of intensity over time. The VICTUS Femtosecond Laser is a versatile platform with cataract, LASIK flap, and therapeutic indications.

If playback doesn't begin shortly Researchers have proven that they can machine and make strips, microstructures and sensors out of spider silk using femtosecond lasers. Just a few days ago it was announced that spiders exposed to water with graphene and carbon nanotubes can make spidersilk that is 3 times stronger than regular spider … Ultrafast laser spectroscopy is a spectroscopic technique that uses ultrashort pulse lasers for the study of dynamics on extremely short time scales (attoseconds to nanoseconds).Different methods are used to examine the dynamics of charge carriers, atoms, and molecules. Many different procedures have been developed spanning different time scales and photon energy ranges; some common methods Femtosecond laser pulses can induce local bulging or plasma ablation of silk with limited structural damage, thus offering a technique for cutting, patterning, bending and welding of silk with Lastek is the exclusive distributor in Australia and New Zealand for more than fifty leading international laser, optic, detection, spectroscopy and imaging manufacturers.
