Abstract
Laser radiation, in addition to possessing unique optical properties such as spatial and temporal coherency, minimum angular beam divergence, polarization, and monochromaticity, may also provide a source of radiant energy of extremely high instantaneous power. Presently available laser sources operated in the Q-spoiled or giant-pulse mode produce megawatts of power in pulses of 20–50-nsec duration. Recently developed mode-locked lasers produce picosecond pulses with associated powers in the gigawatt range. That such high-transient-power densities may be generated from sources with relatively moderate total energy output (i.e., on the order of a few joules) suggests that unique power density—dependent effects must be considered in the evaluation of the effects of such radiation on physical or biological systems.
