The interaction of laser light with biological molecules, and the applications to biology and medicine. The spatial coherence of laser emissions makes it possible to focus beams in small volumes. Consequently, high-power-density irradiations can be obtained, especially with lasers whose energy is delivered in a few nanoseconds or even picoseconds. These two characteristics, combined with the great variety of wavelengths available, have opened up many possibilities of applications to biology and medicine.
