Abstract In this experiment, the effects of gas composition and pressure on the intensity and quality of the plasma induced by a high-energy neodymium glass laser were studied. The experimental results show that the spectral intensity of the plasma in the argon atmosphere is stronger than that in the air when the pressure is the same. For the steel alloy sample, the intensities of the emission spectrum reach the maximum values when the argon pressure is 0.8×105 Pa. The self-absorption phenomena of AlⅡ308.22 and AlⅡ309.27 nm lines strengthen with the increase of the pressure, and even serious self-reversal appears when the pressure is (0.8-0.9)×105 Pa. The temperature of plasma also raises with the increase of the pressure. When the argon pressure is 0.93×105 Pa, the temperature is about 1 500 K higher than that when the argon pressure is about 0.43×105 Pa.
