From page 75... ...
Rapid development of new laser materials in the laboratory and by the laser industry has provided laser users with highly effective wavelengths of adequate power to destroy and alter biological systems and tissues. Hazards that exist from lasers include some unique conditions other than the radiation itself.

From page 76... ...
A good procedure used at the Lawrence Radiation Laboratory" restricts the path of laser beams to heights less than five feet or greater than seven feet so that the beam will not be at eye level. 0ur knowledge of potential ophthalmological hazards that exists from lasers must be extended as laser technology produces higher power devices, both CW and pulsed.

If the laser wavelength is one which the ocular media absorb a known percentage, the additional loss factor can be included. A factor also can be used if the observer is wearing protective goggles, if the attenuation factor of the goggles for the specific wavelength of the laser in use is known.

2 data and incorporated in the slide rule loss factor. Most of the data collected for white light and normally pulsed ruby and neodymium doped glass lasers support a thermal injury model.

From page 79... ...
Ruby laser radiation at 69^3 A is an inefficient visual wavelength and should be selectively absorbed primarily by the red sensitive photopigment, although such effects have never been observed with lasers, pronounced differential adaptation effects have been shown to intense spectral lights (page k] in the third paper)

From page 80... ...
Each worker should have enough indoctrination so as to be able to recognize an unsafe condition, and he should be aware of the individual safety measures that he must observe both for his own protection and the protection of others. The responsibility for safe operation of laser devices must necessarily vary with the situation.

From page 81... ...
Protective goggles should be used at all times in the vicinity of active laser devices. A discussion of the types of eye protective devices available and current research trends follows.
