چکیده
The measurement of short time intervals during the first half of 20 century was limited to intervals longer than one nanosecond. The advent of lasers in 1960 revolutionized the field of time-resolved spectroscopy. The time interval is shortened from 10 to 10 seconds, which made ultrafast experiment grows rapidly. New subfields of science, including femtochemistry and femtobiology, have been created. In this paper, a brief review of ultrafast electron microscopy (UEM), ultrafast laser and ultrafast x-ray imaging will be present.

Nanocomposite materials, including noble metal nanoparticles embedded in a dielectric host medium, are interesting because of their optical properties linked to surface plasmon resonance phenomena. For studding of nonlinear optical properties and/or energy transfer process, these materials may be excited by ultrashort pulse laser with a temporal width varying from some femtoseconds to some hund...

متن کاملExploring the Ultrafast Excited-State Intramolecular Proton Transfer (ESIPT) of β-Diketones in the deep-UV
The photodynamics in symmetric and unsymmetric β-diketones are studied with transient absorption in the deep-UV. Excitation leads to ultrafast ESIPT while further relaxation and isomerization processes depend on the molecular symmetry and solvent environment.
