On the occasion of the return of the old and the new, the Spring Festival of 2009 is about to come, and it is also the beginning of the 39th anniversary of the establishment of the Shanghai Laser Society. I believe that at this moment, all the colleagues who are engaged in laser medicine will be very grateful. At the end of 2008, everyone on the board meeting has expressed their willingness to express their determination and vision for the joint development of laser medicine. Indeed, in the field of laser medicine, new technologies, new equipment, and new lasers emerge in the United States and Europe. A large number of advanced laser devices have been developed in both clinical and medical aesthetics. Generally summarized, there are the following characteristics: 1. A large number of semiconductor lasers emerge, mainly including various infrared wavelength semiconductor lasers, such as 800nm, 810nm, 890nm, 980nm and other laser devices, representative of: dry battery driven semiconductor teeth Laser laser, which is active and compact, can carry out various treatments such as cutting of soft tissues of the department of stomatology, resection of benign tumors, and disinfection of root canals. 2, the introduction of all-solid-state lasers and fully-closed cavity Q-switched lasers, such as KTP-532nm laser, due to the use of all solid-state design, so small size, stable performance, relatively low cost. It has the advantage of being easy to popularize, which is of great significance for the future promotion of laser photodynamic therapy in China. The 755nm alexandrite laser with Q-switched switch is designed with a fully enclosed cavity and the stability is greatly improved. It provides a reliable guarantee for the clinical treatment of pigmented lesions. 3. Continuous development of multi-wavelength lasers, such as 595 nm, 106 nm lasers for the treatment of vascular lesions using dual-wavelength sequential emission technology. 4, a large number of non-stripping lattice laser development, such as 1320nm, 1440nm dual-wavelength infrared laser. 5, the rise of stripping dot matrix lasers, from ultra-pulse CO2 to Er: YAG2940nm and other multi-wavelength large dynamic parameters of the laser. 6, laser technology combines the emergence of a variety of composite technologies such as radio frequency, focused ultrasound, plasma cold spray medical cosmetic equipment. The scope of medical laser treatment has begun to expand to the application of other light sources such as LEDs, etc., so the concept of laser medicine may extend to the field of photonics. On the other hand, domestic research in the same field is very slow. Although China's laser technology itself is not backward, it has international leading technology highlights in the fields of national defense, laser physics and laser processing. However, in the field of medical lasers, it is indeed far behind the foreign technology level. Therefore, how to coordinate the counterparts in related fields in China, research and development and imitation of new imported laser equipment, and focus on the development of innovative medical laser equipment is urgently needed. . 2009 is the year of the international financial crisis, the year of crisis; but there is no shortage of opportunities, welcoming opportunities, and challenging the storm is the time to test us.
