Abstract
In this paper, a transient plasma is produced by focusing the 1064 nm radiation from a Q-switched Nd:YAG onto the one-yuan coin at room temperature in air at atmospheric pressure. Using the iterative Boltzmann algorithm, the plasma electron temperature of the one-yuan coin is calculated as 28144 K. Experiments show that the correlation coefficient increases from 0.197 to 0.997 as the number of iterations increases. Experimental results show that the laser induced one-yuan coin plasma meets the LTE model.
