Ultrafast Laser Pulse Synchronization
Progress in ultrafast science and technology has pushed the temporal resolution to subfemtosecond and attosecond region (Kienberger el at., 2002; Fleischer & Moiseyev, 2006; Corkum & Krausz, 2007; Goulielmakis el at., 2007) and technology exploration in ultrashort pulse generation has made it possible to equip femtosecond lasers that are only a few cycles in duration (Xu el at., 1996; Shirakawa...
متن کاملUltrafast pulse characterization using XPM in silicon
Due to the high-index contrast between the silicon core and silica cladding, the silicon waveguide allows strong optical confinement and large effective nonlinearity, which facilitates low cost chip scale demonstration of all-optical nonlinear functional devices at relatively low pump powers. One of the challenges in ultrafast science is the full characterization of optical pulses in real time....
متن کاملUltrafast double-pulse ablation of fused silica
Ultrafast pump-probe experiments were used to study high-intensity ultrafast pulse-ablation dynamics in fused silica. Two laser pulses with varied time delay and pulse energy were used to irradiate fused silica samples and observe the transient reflectivity and transmissivity of the probe pulse. It was seen that the probe reflectivity initially increased due to the formation of free-electron pl...
متن کاملUltrafast optical pulse shaping: A tutorial review
This paper presents a tutorial on the field of femtosecond pulse shaping, a technology that enables generation of nearly arbitrary, user defined, ultrafast optical waveforms, with control of phase, amplitude, and polarization. The emphasis is on Fourier transform pulse shaping, the most widely applied technique. Selected pulse shaping applications are described, with specific discussion of cohe...
متن کاملFemtosecond pulse imaging: ultrafast optical oscilloscope
A nonlinear optical processor that is capable of real-time conversion of a femtosecond pulse sequence into its spatial image is introduced, analyzed, and experimentally characterized. The method employs nonlinear spectral domain three-wave mixing in a crystal of LiB3O5, where spectral decomposition waves of a shaped femtosecond pulse are mixed with those of a transform-limited pulse to generate...
