Attosecond chirp compensation in water window by plasma dispersion

Dispersion compensation for attosecond electron pulses

Isolated Attosecond Water-Window Pulses driven by 1.8 μm lasers

We generate carrier-envelope phase controlled attosecond continua up to 0.53 keV and corroborate the generation of reproducible and isolated attosecond SXR and water window pulses with duration of 280 as and 322 as, respectively.

Aperiodic CrSc multilayer mirrors for attosecond water window pulses.

Extending single attosecond pulse technology from currently sub-200 eV to the so called 'water window' spectral range may enable for the first time the unique investigation of ultrafast electronic processes within the core states of bio-molecules as proteins or other organic materials. Aperiodic multilayer mirrors serve as key components to shape these attosecond pulses with a high degree of fr...

Attosecond chirp compensation over broadband high-order harmonics to generate near transform- limited 63 as pulses

By generating broadband high-harmonic pulses from neon and compensating for attosecond chirp by the material dispersion of argon, the generation of near transform-limited 63 as pulses was achieved. The spectral phase analysis showed that, without proper compensation, the attosecond chirp of the broadband harmonics caused splitting of attosecond high-harmonic pulses in addition to pulse broadeni...

Adjustable Chirp Injection-Locked 1.55-μm VCSELs for Enhanced Chromatic Dispersion Compensation at 10-Gbit/s

We demonstrate adjustable negative chirp from a directly-modulated, injection-locked 1.55-μm VCSEL by controlling the injection parameters. Chromatic dispersion tolerance is enhanced by greater than 10X at 10-Gb/s compared to that of a free-running VCSELs. ©2008 Optical Society of America OCIS codes: (230.2035) Dispersion compensation devices, (250.7260) Vertical cavity surface emitting lasers
