Space Laser Design.

Abstract

The objective of this research and development study has been to design and fabricate a laboratory brassboard laser which takes into account the power limitations and thermal constraints of the space environment. A Nd:YAG laser has been fabricated which embodies space applicable techniques; in particular, a 300 watt K-Rb alkali-vapor lamp was used as a pump source, and a high pressure flowing nitrogen system was used to cool the laser rod. In the course of the study program, the thermal problems associated with the use of the lamp were examined and data on the effectiveness of the cooling system was accumulated. This report contains the results obtained during the program, the conclusions based on these results, and recommendations for further use and development of the device. Data were also accumulated on the output power and mode quality of the laser, as well as data which bears on the thermal lensing and thermal birefringence in the Nd:YAG rod. (Author)
