Terawatt Cr:LiSrAIF(6) laser system.
We have developed a compact flash-lamp-pumped Cr:LiSrAlF(6) (Cr:LiSAF) laser system capable of producing peak powers in excess of 1 TW. Chirped-pulse amplification in a Cr:LiSAF regenerative amplifier produces 8-mJ pulses at a 5-Hz repetition rate. Further amplification in Cr:LiSAF yields recompressed pulse energies of 150 mJ and a pulse duration <135 fs at a 0.5-Hz repetition rate.
متن کاملOptimization of a Terawatt Free Electron Laser∗
There is great interest in generating a terawatt (TW) hard X-ray free electron laser (FEL) that will enable coherent diffraction imaging of complex molecules like proteins and probe fundamental high-field physics. A feasibility study of producing such pulses was carried out employing a configuration beginning with an SASE amplifier, followed by a “self-seeding” crystal monochromator, and finish...
متن کاملTwo-color terawatt laser system for high-intensity laser-plasma experiments
We report a two-color terawatt laser system for use in controlling laser-plasma instabilities. The system includes a commercial 45 TW Ti:Sapphire laser system at 800 nm, temporally synchronized with a 1 TW CPA Raman-Ti:Sapphire hybrid laser centered at 873nm that we designed and built to complement the 800 nm system. The two-color system will be used to seed, enhance, suppress, or otherwise con...
متن کاملAdvanced Ultrafast Laser Concepts at the Tens of Terawatt Level
The Laser Plasma Laboratory’s multi-terawatt femtosecond laser (MTFL) will be undergoing a laser upgrade in the upcoming months. The current chirped pulse amplification system will be upgraded from 25 mJ to 500 mJ. Amplification processes at high intensities such as these introduce the problem of gain narrowing. Fastlite’s DAZZLER (an AOPDF) was used to shape the laser pulse before amplificatio...
متن کاملMultiple filamentation of terawatt laser pulses in air.
The filamentation of femtosecond light pulses in air is numerically and experimentally investigated for beam powers reaching several TW. Beam propagation is shown to be driven by the interplay between intense, robust spikes created by the defects of the input beam and random nucleation of light cells. Evolution of the filament patterns can be qualitatively reproduced by an averaged-in-time (2D+...
