Nonlinear optical effects that would alter the frequency spectrum of an ultrashort pulse are not considered. The YFOA femtosecond fiber laser is designed for stable generation of an ultra-short laser pulse train. The device contains Yb-doped active fiber, pump diodes, polarization control and dispersion control elements, electronic power supply and control system. 2017-08-19 DOI: 10.1002/sia.6545 Corpus ID: 104921418.

Spider femtosecond

Spider silk is a tough, elastic and lightweight biomaterial, although there is a lack of tools available for non-invasive processing of silk structures. Here we show that nonlinear multiphoton interactions of silk with few-cycle femtosecond pulses allow the processing and heterostructuring of the material in ambient air. 02.09.2019 TiF-100ST-F6 femtosecond Ti:S oscillator with Frep locking for multiphoton microscopy at CANDLE, Armenia. 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. Several years later, another femtosecond-pulse-intensity-and-phase measurement technique emerged, called spectral interferometry for direct electric-field reconstruction (SPIDER), which retrieves the pulse spectral phase by interfering two pulse replicas up-converted to slightly different center frequencies.

When threatened, most animals, spiders included, exhibit what is known as the 21 Jan 2014 Scientists returned to the Amazon rainforest in December to collect data on one of their biggest finds of 2012: a spider that uses insect corpses 3.2 Chirped pulse amplification.

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.
