摘要：

We have newly developed a two dimensionally (2D) space-resolved spectrometer for an ultra high intense laser plasma experiment. Output of this data, we can obtain four dimensional informations: space(2D), 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 mu m. Back-scattered light was measured from plasmas irradiated with an ultra-intense laser pulse at laser intensity 10(19) W/cm(2). The obtained spectra show distinctive difference depending on both spatial and intensity profiles.
