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

It features Swept Source (2S) OCT Technology for live, online, continuous viewing of the entire procedure for all procedures. Summary of the features on the VICTUS Femtosecond Laser Platform Featuring a built-in two-photon absorption (TPA) detector, this autocorrelator is ideal for measuring ultrafast femtosecond and picosecond laser pulses at wavelengths from 700 to 1100 nm. Once programmed, the femtosecond laser automatically creates perfect arcs and incisions, painlessly, which are customized to the individual patient’s needs. And although highly skilled surgeons may be threatened by the technology, it will quickly become the standard of modern cataract surgery.

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.

The spider leaps away, trailing behind it a pristine line of silk. And now Singh has what he needs. To build things out of the silk, Singh’s group uses a femtosecond laser. This is a tool that sends out powerful pulses of light that are very short.

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. The orientation of the β-sheets was more unidirectional when the silk was extended.

It delivers pulses with a maximum energy of 30 uJ at up to 1 MHz repetition rate. In situ characterization and control of the phase of broadband femtosecond pulses in microscopy can be achieved with a novel simplified scheme based on spectral shear interferometry for direct electric field reconstruction (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 Abstract.

Other pulse diagnostic devices, such as e.g. autocorrelators, are typically designed for p-polarized input, matching the p-polarized output from the venteon as well as the taccor series of oscillators. We exploit the nonlinear multiphoton interaction of a few-cycle femtosecond (fs) pulse with viscoelastic microfibers in order to produce nanoscale grooves on its surface. The single fs pulse has been extracted from 1 kHz pulse train by double-shutter gating technique by placing two mechanical shutters in the beamline and simultaneously triggering them with a controlled delay.

The TiF-100ST-F6 femtosecond Ti:S oscillator with a built-in pump laser, also equipped with the ALock PLL electronics unit for pulse repetition rate locking to an external RF source has been installed at the Synchrotron Research Institute’s CANDLE facility in Armenia. Spectral Phase Interferometry for Direct Electric-field Reconstruction (SPIDER) is a specific implementation of spectral shearing interferometry for the complete temporal characterization (or more specifically the spectral phase) of ultrashort optical pulses. SPIDER and FROG measurements are compared for one stable and two unstable trains of pulses.

Spider silk is a biomaterial that has come to intrigue many in recent times. researchers at IISER Mohali have demonstrated how to overcome these challenges using a femtosecond laser pulse.

Each pulse replica is upconverted with a different frequency slice, and consequently, the upconverted pulses have a spectral shift. The SPIDER (Spectral Phase Interferometry for Direct Electric field Reconstruction) system provides precise phase-amplitude measurement of ultrashort laser pulses. The device is widely used for on-line tuning of amplifier systems. The device is used to measure spectral phase, spectral intensity and temporal intensity. Overview 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. This video demonstrates the initial stage of laser cataract surgery using a femtosecond laser to cut an anterior capsulotomy and fragment the lens nucleus us LX Spider is a highly compact instrument for the characterization of femtosecond laser pulses in the range of 16 … 200 fs.
