Marla L. Dowell, Christopher L. Cromer, Richard D. Jones, Darryl A. Keenan, Thomas Scott
Current and future laser measurement services at 157, 193, and 248 nm will be reviewed. Laser power and energy measurements at 193 nm will be presented, electrical calibration issues will be reviewed. We report an overall calibration uncertainty of laser power and energy meters of less than 2%. Characterization measurement for ultraviolet materials also will be discussed.
