The densities of argon excited states (1s3, 1s4, and 1s5) and the gas temperature of argon microplasma were measured by diode laser absorption. A 900-MHz microstrip split-ring resonator was used to excite the argon microplasma with gas pressures between 1 and 760 torr. The line-integrated excited-state densities and gas temperature of these states were estimated by the integrated absorption and broadening of the measured lineshapes, respectively. The excited-state densities were found to be… CONTINUE READING
