【Abstract】 The X ray spectra emitted from laser produced Au plasmas in the range 0.3~0.4nm are analyzied and interpreted by using the Spin Orbit Splitted Array model. The plasmas are created by using a beam of a frequency tripled 1.05μm Nd glass laser focused onto a microdot target of gold.The pulse width was 800ps and the laser energy is about 12J. The emitted X ray is analyzed by a pentaerythritol(PET) crystal spectrograph and recorded on Tianjing New III X ray films. On the assumption of the mono temperatured local thermodynamical equilibrium approximation, the electronic temperature is obtained from the intensity ratio of two unresolved transition arrays, and the experimental spectra is simulated.更多还原
