Phase-only synthesis of ultrafast stretched square pulses.

چکیده
We report the generation of square temporal-shape pulses with no loss of spectral bandwidth, using an analytic expression for the spectral phase modulation dependent only on the input spectrum and stretching factor. We demonstrate numerically and experimentally conversion of 40fs pulses into 150 times longer flat top pulses with sharp on and off fronts. Applications in pulse amplification and free electron lasers are considered.

Ultrafast Stretched-Pulse Fiber Laser Mode-Locked by Carbon Nanotubes
Ultrafast fiber sources having short pulses, broad bandwidth, high energy, and low amplitude fluctuations have widespread applications. Stretched-pulse fiber lasers, incorporating segments of normal and anomalous dispersion fibers, are a preferred means to generate such pulses. We realize a stretched-pulse fiber laser based on a nanotube saturable absorber, with 113 fs pulses, 33.5 nm spectral ...
متن کاملShaping of femtosecond pulses using phase-only filters designed by simulated annealing
We describe generation of shaped femtosecond waveforms by using frequency-domain phase-only filters designed by numerical optimization techniques. The task of filter design for pulse shaping in the time domain is directly analogous to the design of phase-only filters for beam shaping and array generation in the spatial domain. We experimentally tested phase filters that were designed to produce...
متن کاملNovel laser system for ultrafast spectroscopy
The design and performance of a cavity-dumped Ti:sapphire (CD-TS) oscillator and short pulse-pumped amplifier system is presented. Dumped pulses as short as 12 fs duration and 60 nJ in energy, with 70%-80% dumping efficiency are made possible by a stretched dumper-arm configuration. The oscillator yields stable, reliable, and reproducible pulses. Pulse duration and phase structure are analyzed ...
متن کاملSynthesis of diamond-like phase from graphite by ultrafast laser driven dynamical compression
Rapid variations of the environmental energy caused by ultrashort laser pulses have induced phase transitions in carbon allotropes, therefore bringing the promise of revealing new carbon phases. Here, by exposing polycrystalline graphite to 25 fs laser pulses at 4 J/cm(2) fluence under standard air atmosphere, we demonstrated the synthesis of translucent micrometer-sized structures carrying dia...
متن کاملTerahertz waveform synthesis via optical rectification of shaped ultrafast laser pulses.
We demonstrate the use of optical pulse-shaping technique in conjunction with difference frequency generation in a non-linear optoelectronic crystal for generating synthesized waveforms at terahertz frequencies. Spectral phase modulations, programmed using Gerchberg-Saxton algorithm and prepared in a spatial light Fourier filter, produce tailored terahertz pulses, including chirped pulses, zero...
