ABSTRACT:
An improved medical laser treatment system and method generates a beam of laser energy at a predetermined wavelength; transmits the beam of laser energy along a path to a medical treatment site; delivers to the medical treatment site an insufflating gas which is absorbent at the predetermined wavelength; and introduces into the path of the beam of laser energy a non-absorbent purge gas which is transparent to the predetermined wavelength of the laser, at a flow rate for opposing the influx of insufflating gas to reduce the resonant absorption of the laser beam energy.
