We have studied Sn plasma which is produced by different laser wavelengths and different pulse durations. Laser produced Sn plasma is currently considered as a candidate for an EUV radiation source. Studied Sn as an efficient target to produce 13.5 nm EUV radiation, has many applications such as lithography application. As well as laser produce Sn plasma is consider as a lasing media at 11.9 nm, as it is relatively produced high gain. The research consists of three topics: First, the electron temperature and density were estimated from the analysis of spectral data. The electron temperature...
