Abstract

We have examined how different cleaning processes affect the laser-induced damage threshold of antireflection coatings for large dimension, Z-Backlighter laser optics at Sandia National Laboratories. Laser damage thresholds were measured after the coatings were created, and again 4 months later to determine which cleaning processes were most effective. There is a nearly twofold increase in laser-induced damage threshold between the antireflection coatings that were cleaned and those that were not cleaned. Aging of the coatings after 4 months resulted in even higher laser-induced damage thresholds. Also, the laser-induced damage threshold results revealed that every antireflection coating had a high defect density, despite the cleaning process used, which indicates that improvements to either the cleaning or deposition processes should provide even higher laser-induced damage thresholds.

How reduced vacuum pumping capability in a coating chamber affects the laser damage resistance of HfO₂/SiO₂ antireflection and high-reflection coatings

Journal Article Field, Ella S. ; Bellum, John C. ; Kletecka, Damon E. - Optical Engineering

Here, optical coatings with the highest laser damage thresholds rely on clean conditions in the vacuum chamber during the coating deposition process. A low-base pressure in the coating chamber, as well as the ability of the vacuum system to maintain the required pressure during deposition, are important aspects of limiting the amount of defects in an optical coating that could induce laser damage. Our large optics coating chamber at Sandia National Laboratories normally relies on three cryo pumps to maintain low pressures for e-beam coating processes. However, on occasion, one or more of the cryo pumps have been out ofmore »« less

Laser-damage thresholds of thin-film optical coatings at 248 nm

Conference Milam, D ; Rainer, F ; Lowdermilk, W H

We have measured the laser-induced damage thresholds for 248 nm wavelength light of over 100 optical coatings from commercial vendors and research institutions. All samples were irradiated once per damage site with temporally multi-lobed, 20-ns pulses generated by a KrF laser. The survey included high, partial, and dichroic reflectors, anti-reflective coatings, and single layer films. The samples were supplied by ten vendors. The majority of samples tested were high reflectors and antireflective coatings. The highest damage thresholds were 8.5 to 9.4 J/cm/sup 2/, respectively. Although these represent extremes of what has been tested so far, several vendors have produced coatingsmore »« less

Influence of deposition parameters on laser-damage threshold of silica-tantala AR coatings

Journal Article Milam, D ; Lowdermilk, W H ; Rainer, F ; ... - Appl. Opt.; (United States)

A series of 4-layer silica-tantala antireflection coatings was deposited under 18 different combinations of substrate temperature (175, 250, and 325 /sup 0/C), oxygen pressure (0.5, 1.0, and 2.0 x 10/sup -4/ Torr), and rate of deposition (1.5 and 5 A/sec). Measurements of laser-damage threshold for 1064-nm, 1-nsec pulses, average absorption, net stress, and reflectivity were then made on these coatings. Coatings deposited at the lowest temperature had the highest damage thresholds. Damage thresholds were found not to be directly related to average absorption or net stress. Coatings deposited on fused silica substrates which had been polished by a bowl-feed processmore »« less

Pulse duration dependence of 1064-nm laser damage thresholds of porous silica antireflection coatings on fused silica substrates

Conference Milam, D ; Thomas, I M ; Weinzapfel, C ; ...

We used 1064-nm pulses with durations of 1, 5, 9 ns to measure laser-damage thresholds of 10 porous silica antireflection coatings deposited from both methanol and ethanol solutions containing silica particles with diameters of 10-20 nm. The median thresholds measured at the three pulse durations, 10.8 J/cm/sup 2/, 26.5 J/cm/sup 2/, and 38 J/cm/sup 2/, scaled as pulse duration to the 0.56 power. 4 refs., 3 figs., 1 tab.
