Pulsed-Laser Metrology at NIST

February 1, 2001
Author(s)
Marla L. Dowell
Lasers and laser metrology have become an important part of our daily lives. Since the inception of the first operable laser 41 years ago, there has been explosive growth in the number of new applications of laser technology; from supermarket scanners to

New Developments in Deep Ultraviolet Laser Metrology for Photolithography

January 1, 2001
Author(s)
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

B D. Paul, Marla L. Dowell, Alan Gallagher, J W. Cooper
We report observations of conical emission from a pulsed laser beam with incident laser power, detuning, and beam diameter matched to a range of single, steady-state filaments. The beam thus propagates with nearly constant diameter through 5 cm of

Self-focused Light Propagation in a Fully Saturable Medium: Theory

October 1, 1995
Author(s)
Marla L. Dowell, B D. Paul, Alan Gallagher, J W. Cooper
We report observations of self-focusing and filamentation of ~3 ns laser pules in strontium (Sr) vapor. The expermental arrangement consits of a Sr vapor cell and a pulsed Nd:YAG pumped dye laser tuned to the blue of the 461 nm transition in Sr. The
