Irradiation of biological specimens by a cw Ar(+) laser and temperature distributions

Temperature measurements related to the interaction of the 5145-A line of a cw argon laser with in vivo whole biological specimens are presented, both in TEM(00), single frequency, and multimode, multifrequency operating conditions. A simple mathematical model for the evaluation of the temperature trends in a region outside the direct impact of the laser beam is also proposed.
