Abstract In the present paper, the effects of argon atmosphere at high pressure(0.2-1.1 MPa) on the radiation intensity of the plasma induced by a high energy neodymium glass laser (energy ～30 J, pulse width 0.7 ms) were studied by recording the photograph and spectra of the plasma as well as measuring the ablated mass. The experimental results show that the volume of the plasma was compressed, the temperature increased, and the lightness enhanced significantly when pressure was raised. Under our experimental condition, the radiation intensities of the plasmas were enhanced with the increase in the gas pressure; but the ablated mass of the sample decreased. The measured results are discussed, combined with the process of the experiment.
