Abstract
We have newly developed a 2D space-resolved spectrometer for an ultra high intense laser plasma experiment. Output of this data, we can obtain 4D information: space, spectrum, and intensity. An optical fiber bundle is combined with a Cross Czerny-Turner type spectrometer to acquire 2D space- resolved spectrum. This has the spectral resolution 0.8 nm and the space 8 micrometers . Back-scattered light was measured from plasmas irradiated with a n ultra-intense laser pulse at laser intensity 1019 W/cm2. The obtained spectra show distinctive difference depending on both spatial and intensity profiles.
