Objective:

To determine new biophysics underlying human cornea and skin exposure from single laser pulses, between 1.0 millisecond (ms) to 50 femtoseconds (fs), produced in the 350 nanometers (nm) to 2000 nm wavelength region. The Dutch belted rabbit (Oryctolagus cuniculus) cornea and Yucatan mini pig (Sus scrofa domestica) skin, will be used to assess damage mechanisms and thresholds from novel exposures with immediate military relevance.

 

Approach:

The proliferation of lasers throughout the world has increased the use and development of high-energy, short-pulsed laser systems for military application. A critical research area is the 350 to 2000 nm laser wavelengths for cornea and skin injury. Military systems use energies and pulses in this regime where few data points exist upon which safety of Department of Defense (DoD) personnel is based for cornea and skin. Therefore, with this lack of data to substantiate a safety standard, there is a pressing need to further investigate in this area of environmental health. We will determine damage thresholds in Dutch belted rabbit corneas and Yucatan mini pig skin for single pulse, collimated beam exposures at wavelengths between 350 to 2000 nm and pulses ranging from 1.0 ms to 10 fs in duration. Along with the determination of appropriate threshold limits for laser exposure, we will determine the appropriate biochemical damage mechanisms relevant to cornea and skin laser damage through carefully designed experiments that will allow biochemical assays, histopathology and theoretical modeling.

Rats, mice, birds, amphibians and other animals have been excluded from coverage by the Animal Welfare Act. Therefore research facility reports do not include these animals. As a result of this situation, a blank report, or one with few animals listed, does not mean that a facility has not performed experiments on non-reportable animals. A blank form does mean that the facility in question has not used covered animals (primates, dogs, cats, rabbits, guinea pigs, hamsters, pigs, sheep, goats, etc.). Rats and mice alone are believed to comprise over 90% of the animals used in experimentation. Therefore the majority of animals used at research facilities are not even counted.
