The development of laser medicine in China is correlated with the development of laser science in China. After the first Chinese laser, ruby laser came into being in 1961, Chinese medical scientists began to do the studies about laser medicine in the middle 1960s. For example, ruby laser was adopted for the retina coagulation experiment in 1965. Since 1970s, through the free choice of utilizing Co2, He-Ne, Nd:YAG argon, ruby lasers, laser surgery and medicine has been widely applied to the treatment for diseases of the eyes, ENT, dermatology, surgery, gynecology, tumors and diseases suitable to physical therapy or acupuncture with satisfactory effects. In June 1977, a nation-wide laser medicine symposium was held at Wuhan, Hubei Province with 200 participants including medical doctors and laser technologies from 23 provinces and municipal towns. Till the end of seventies, utilization of lasers has been extended to Nd glass laser, N laser and tunable dye lasers. The scope covered most of the clinical sections. After Dr. Thomas J. Dougherty developed the PDT for cancers in Roswell Park Memorial Institute in Buffalo in late 1970s and Professor Yoshihiro Hayata successfully applied the PDT in clinical treatment for lung cancer in 1980, Chinese pharmacists successfully produced the Chinese HpD and the first case of PDT, a lower eyelid basal cell carcinoma patient was treated with the Chinese laser equipment in 1981 in Beijing. Its success brought attention establishing a research group supported by the government in 1982. The members of the group consisted the experts on preclinical and clinical research, pharmaceutical chemistry, laser physicists and technologists. A systemic research on PDT was then carried out and obvious result was achieved. The step taken for PDT also accelerated the researchers on other kinds of laser medicine and surgery because the medical doctors had begun to master the knowledge about laser science. The prosperous situation of rapid development of laser science, bio-medical lasers, laser medicine and surgery as well as PDT was prolonged in the whole nineteen eighties.
