摘要

Abstract: When used in continuous wave (cw) mode the CO$-2$/ laser is an effective tool for vaporizing unwanted tissue, however, there is the possibility of the accumulation of thermal energy in the good tissue close to the point of treatment. If this thermal energy is high then post operative pain and scarring could result. This is avoidable by delivering the energy in short pulses with the gap between those pulses being greater than the thermal relaxation time of the tissue (which can vary according to tissue type that is typically 0.5 to 3.0 ms). Simply chopping the laser beam rapidly would produce the desired thermal effect but would waste a large percentage of the laser energy and greatly extend the treatment time since the average output power of the laser is compromised. The ideal scenario is where the laser power is enhanced for the on period producing an average power similar to that obtained in cw mode. !0
