Safety aspects of laser fusion research at the Los Alamos Scientific Laboratory

In 1972, the Los Alamos Scientific Laboratory initiated an organized effort — by forming a Laser Research and Technology Division — to investigate the practicability of using the energy in focused laser beams to confine fusion targets of deuterium for themonuclear burn and subsequent extraction of heat for generating electricity. Criteria for evaluating hazards in high energy laser environments were only in formative stages, and many associated hazards were not contemplated. Fundamental biological data for fast-pulsed lasers was also lacking. This paper describes the control measures instituted and eye-wear developed for the protection of employees. Results of threshold damage experiments are summarized and a programme designed for comprehensive control of the hazards is outlined. To date no biological damage has been experienced by any employee.
