THE MEASUREMENT OF SCATTERING LOSS IN CAVITY OF A CW CHEMICAL OXYGEN-IODINE LASER

If“snow Crystals”, formed in the course of depriving the vapor in the singlet oxygen flow are taken into cavity with flow, the scattering loss of CW chemical oxyen -iodine laser at 1.315μm will be increased. So in this paper, by the means of double optical path, using a He -Ne laser as a probe laser, the scattering loss whether the " snow crystals" are appeared adn flow into the cavity is measured. The scattering loss is measured smaller than 1%, it shows that the singlet oxygen is in high quality before it flow into the cabity. This result also provides the data of scattering loss in cavity for resonator design.
