Publikováno v: Laser-Induced Damage in Optical Materials: 2008.

Laser-induced growth of optical damage often determines the useful lifetime of an optic in a high power laser system. We have extended our previous work on growth of laser damage in fused silica with simultaneous 351 nm and 1053 nm laser irradiation

Growth of laser damage on the input surface of SiO 2 at 351 nm

Autor: Eugene E. Donohue, Alexander M. Rubenchik, Mary A. Norton, William G. Hollingsworth, Mary L. Spaeth, Richard P. Hackel, Michael D. Feit

Publikováno v: SPIE Proceedings.

Growth of laser initiated damage is a potential lifetime limiter of laser optics. While laser initiated damage occurs most often on the exit surface of optical components, some damage sites can occur on the input surface. We have investigated the gro

Impact of contaminates on the laser damage threshold of 1ω HR coatings

Autor: Christopher J. Stolz, Richard P. Hackel, Mary A. Norton, Kalvin Listiyo, William G. Hollingsworth, Eugene E. Donohue, James A. Pryatel

Publikováno v: SPIE Proceedings.

In operational laser systems, it is often difficult to keep optical components completely free of foreign material. We have investigated the performance of high damage threshold 1.053 {micro}m high reflectors in the presence of surface contaminants.

Growth of laser damage in SiO 2 under multiple wavelength irradiation

Autor: Michael D. Feit, Eugene E. Donohue, Mary L. Spaeth, Richard P. Hackel, Mary A. Norton, William G. Hollingsworth, Alexander M. Rubenchik

Publikováno v: SPIE Proceedings.

In laser systems using frequency conversion, multiple wavelengths will be present on optical components. We have investigated the growth of laser initiated damage in fused silica in the presence of multiple wavelengths. In particular, we measured gro

Experimental study of 351-nm and 527-nm laser-initiated surface damage on fused silica surfaces due to typical contaminants

Autor: Eugene E. Donohue, Michael A. Johnson, Mary A. Norton, John Honig, William G. Hollingsworth

Publikováno v: SPIE Proceedings.

Optics damage under high-intensity illumination may be the direct result of laser light interaction with a contaminant on the surface. Contaminants of interest are small particles of the materials of construction of large laser systems and include al

Publikováno v: SPIE Proceedings.

Previously, we reported preliminary results for commercial thin borosilicate glass sheets evaluated for use as a frequently-replaced optic to separate the radiation and contamination produced by the inertial confinement fusion experiments in the Nati

Publikováno v: Laser-Induced Damage in Optical Materials: 2002 and 7th International Workshop on Laser Beam and Optics Characterization.

We report an experimental investigation of mitigating surface damage growth at 351 nm for machine-finished DKDP optics. The objective was to determine which methods could be applied to pre-initiated or retrieved-from-service optics, in order to stop

Publikováno v: Laser-Induced Damage in Optical Materials: 2000.

The effective lifetime of optics is limited by both laser-induced damage and the subsequent growth of laser initiated damage sites. We have measured the growth rate of laser-induced damage in fused silica in both air and vacuum at 527 nm. For damage
