Broad spectral range few-cycle laser pulses characterization by using a FASI device

Researchers from the Shanghai Institute of Optics and Fine Mechanics (SIOM) of the Chinese Academy of Sciences (CAS) have developed a simple device called frequency-resolved optical gating and self-referenced spectral interferometry (FASI), which combines the frequency-resolved optical gating (FROG) and self-referenced spectral interferometry (SRSI) in a single device based on the same third-order nonlinear effect of the transient grating (TG). The result was published in Optics & Laser Technology.
