pulse. 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

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.

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. Advances in femtosecond methods are crucial to the understanding of ultrafast phenomena in nature. Photodissociation and femtosecond probing. 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.

Input pulse duration from 5 fs. Suitable for oscillators and amplifiers. Real-time measurements. Single-shot mode. SPIDER. Spectral Phase Measurement System. The unit is designed for measurements of spectral phase and spectral intensity of femtosecond pulses.

We present the SPIDER is a technique for measurement spectral phase of femtosecond optical pulses. In SPIDER setup, two replicas of the input pulse to be characteri zed are generated with a fixed time delay between them. These two replica pu lses are then upconverted by sum-frequency mixing with a strongly chirped pulse derived from the same original input pulse.

SPIDER can directly extract the spectral phase and reconstruct the pulse waveform; it is therefore suitable for accurate and fast measurement of ultrashort optical pulses, especially for femtosecond optical pulses. In this paper, we introduce a new spectral phase retrieval technique for accurate waveform reconstruction of femtosecond optical

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 …

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. How short?

An asymmetric \b{eta}-sheet structure of spider silk is said to induce optical second harmonic generation. In this paper, using an in-house non-scanning type femtosecond pulse laser second harmonic generation microscope, we characterized the behavior of the \b{eta}-sheet of spider silk under an applied external force. The SPIDER technique requires two interferometers, a stretcher, a second-harmonic crystal, a high-resolution spectrometer, and a sophisticated software program for spectral phase characterization. Both methods are reliable and accurately measure the spectral phase of femtosecond laser pulses.

SPIDER retrieves only the nonrandom component (the coherent artifact) of these pulse trains A comprehensive comparison of SPIDER and FROG techniques is difficult, because there are many variants of both methods, which have specific advantages under certain circumstances.

spectroscopy. This would not have been possible without the development of femtosecond lasers. 1.2. Femtosecond laser Researchers strive to develop shorter pulses, more energetic pulses and higher repetition rates. The most important techniques that have resulted in amplified femtosecond pulsed lasers are presented in the paragraph below.

These two replica pu lses are then upconverted by sum-frequency mixing with a strongly chirped pulse derived from the same original input pulse. 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.
