Development of laser ice-cutting apparatus / Edward Zeller, Gisela Dreschhoff, Claude M. Laird.
Title: | Development of laser ice-cutting apparatus / Edward Zeller, Gisela Dreschhoff, Claude M. Laird. |
Author(s): | Zeller, Edward. Dreschhoff, Gisela. Laird, Claude M. |
Date: | 1991 review. |
In: | Antarctic Journal of the United States. (1991 review.), Vol. 26(5) (1991 review) |
Abstract: | During 1990-91 field season at Windless Bight, near Ross Island, 25 watt continuous infrared CO₂ laser was used to cut individual firn cores for sample preparation. Advantage of device is that beam is emitted at infrared wavelength, which is absorbed in very short distance in ice; beam cuts cleanly and rapidly through firn and ice and is operated with standard optical systems. Some refinements are described. |
Notes: | Antarctic Journal of the United States. Vol. 26(5) :89-91 (1991 review). |
