Ultrashort Pulses
Ultrashort pulses usually are defined as those lasting less than a nanosecond. Low-energetic ultrashort pulses can be used, for instance, as a probe for studying the dynamics of ultrafast processes. Amplifying these pulses can deliver extremely high peak power, allowing applications such as laser particle acceleration, or γ-ray generation via Compton scattering on relativistic electrons. Existi...
متن کاملPlasmonic generation of ultrashort extreme-ultraviolet light pulses
Ultrashort extreme-ultraviolet pulses are a key tool in timeresolved spectroscopy for the investigation of electronic motion in atoms1,2, molecules3 and solids4. High-harmonic generation is a well-established process for producing ultrashort extreme-ultraviolet pulses by direct frequency upconversion of femtosecond near-infrared pulses5–7. However, elaborate pump–probe experiments performed on ...
متن کاملUltrashort Optical Pulses in the Linac Coherent Light Source
The Linac Coherent Light Source (LCLS) project at the Stanford Linear Accelerator Center (SLAC) will produce intense, coherent 0.15 nm x-rays, with an expected peak brightness many orders of magnitude greater than existing x-ray sources and energy density as high as 4 x 10 watts/cm. These x-rays are produced by a single pass of a 15 GeV electron beam through a long undulator. The 15 GeV electro...
متن کاملSelf-organized nanogratings in glass irradiated by ultrashort light pulses.
Periodic nanostructures are observed inside silica glass after irradiation by a focused beam of a femtosecond Ti:sapphire laser. Backscattering electron images of the irradiated spot reveal a periodic structure of stripelike regions of approximately 20 nm width with a low oxygen concentration, which are aligned perpendicular to the laser polarization direction. These are the smallest embedded s...
متن کاملDynamic properties of bacteriorhodopsin exposed to ultrashort light pulses.
Bacteriorhodopsin (BR) in its metastable form was used for pulsed holographic recording at lambda~400nm . It is shown that the properties of BR are insensitive to changes in the writing light's pulse width. When holograms are recorded in the BR stable form (lambda~600 nm) , the sensitivity of the medium and the diffraction efficiency of those holograms are reduced proportionally to the decrease...
