Abstract
The characterization of ultra-short laser pulses is critical for a variety of scientific and industrial applications from lightmatter interaction to micromachining. We proposed a multispectral measurement method based on the ePIE technique combined with wavelength scanning and set up an integrated device with simple structure and high reliability. Experimentally, we demonstrated the spatio-spectral complex amplitude over the full spectrum of ultra-short pulse with a resolution of 22μm. The full spatio-spectral characterization is of great significance to improve the quality of ultrashort lasers.
