Journal ArticleDOI
Energy balance of optical breakdown in water at nanosecond to femtosecond time scales
Alfred Vogel,Joachim Noack,Kester Nahen,Dirk Theisen,Stefan Busch,Ulrich Parlitz,Daniel X. Hammer,Gary D. Noojin,Benjamin A. Rockwell,Reginald Birngruber +9 more
TL;DR: In this article, the authors investigated the partition of laser energy between these channels during breakdown in water, and found that the absorption at the breakdown site first decreases strongly with decreasing pulse duration, but increases again for < 3p s.
Journal ArticleDOI
A procedure for multiple-pulse maximum permissible exposure determination under the Z136.1-2000 American National Standard for Safe Use of Lasers
Robert J. Thomas,Benjamin A. Rockwell,Wesley J. Marshall,Robert C. Aldrich,Sheldon A. Zimmerman,R. James Rockwell +5 more
TL;DR: The current national consensus standard for laser safety in the United States is the American National Standard for Safe Use of Lasers (ANSI Z136.1-2000).
Journal ArticleDOI
Laser-induced breakdown in aqueous media
TL;DR: In this paper, the effects of laser-induced breakdown in aqueous media were investigated and applications of laser induced breakdown in liquids in liquids were discussed. But none of these applications were considered in this paper.
Journal ArticleDOI
Influence of pulse duration on mechanical effects after laser-induced breakdown in water
TL;DR: In this article, the influence of the pulse duration on the mechanical effects following laser-induced breakdown in water was studied at pulse durations between 100 fs and 100 ns at a cuvette containing distilled water.
Journal ArticleDOI
Theory and simulation on the threshold of water breakdown induced by focused ultrashort laser pulses
Q. Feng,Jerome V. Moloney,Alan C. Newell,Ewan M. Wright,Kirk W. Cook,Paul K. Kennedy,Daniel X. Hammer,Benjamin A. Rockwell,Charles Thompson +8 more
TL;DR: In this paper, a comprehensive model for focused pulse propagation in water was developed, which incorporates self-focusing, group velocity dispersion, and laser-induced breakdown in which an electron plasma is generated via cascade and multiphoton ionization processes.
