Electron thermalization and relaxation in laser-heated nickel by few-femtosecond core-level transient absorption spectroscopy

چکیده
Thermalization and relaxation of photoexcited carriers play an important role in ultrafast demagnetization photoinduced phase transitions. However, direct observation carrier thermalization metals is highly challenging due to its fast timescale. Here, the authors track electrons nickel real time with few-femtosecond core-level transient absorption spectroscopy. In addition, a method extract temperature from spectrum proposed verified by experimental results. This enables further applications spectroscopy explore element- and, hence, domain-specific dynamics metallic alloys multilayers.

متن کاملFemtosecond laser Fourier transform absorption spectroscopy.
A femtosecond mode-locked laser is used for what is believed to be the first time as a broadband infrared source for high-resolution Fourier transform absorption spectroscopy. A demonstration is made with a Cr(4+):YAG laser. The entire nu(1)+nu(3) vibration-rotation band region of acetylene, observed after passing through a single-pass 80-cm-long cell, is simultaneously recorded between 1480 an...

The excited state dynamics of two generations perylenediimide chromophores substituted in the bay area with dendritic branches bearing triphenylamine units as well as those of the respective reference compounds are investigated. Using single photon timing and multi-pulse femtosecond transient absorption experiments a direct proof of a reversible charge transfer occurring from the peripheral tri...
متن کاملIn situ characterization of few-cycle laser pulses in transient absorption spectroscopy.
Attosecond transient absorption spectroscopy has thus far been lacking the capability to simultaneously characterize the intense laser pulses at work within a time-resolved quantum-dynamics experiment. However, precise knowledge of these pulses is key to extracting quantitative information in strong-field highly nonlinear light-matter interactions. Here, we introduce and experimentally demonstr...
