GB/T4799—2001
This standard is compiled in accordance with the requirements of GB/T1.3—1997 "Guidelines for Standardization Work Unit 1: Rules for Drafting and Presenting Standards Part 3: Regulations for Writing Product Standards" and the needs of laser research, production and sales. The original GB/T4799—1984 "Method for Naming Gas Laser Models" was limited to gas lasers; the original GJB/Z43.2—1993 "Military Laser Device Series Spectrum Solid State Lasers" Appendix A "Method for Naming Solid State Laser Models (reference)" was also limited to solid state lasers. This standard is a comprehensive revision of the relevant contents of the above two standards, and the scope has been expanded to make it a complete standard document applicable to all types of lasers.
Lasers can be divided into gas, solid, semiconductor, liquid and free electron lasers according to the working material. This standard includes the first four types of lasers, among which the model naming of semiconductor lasers and liquid lasers is newly added. Because free electron lasers have not yet been seen in China, this standard has not been included in it for the time being.
Compared with Appendix A of GB/T4799 and GJB/Z43.2-1993, this standard adds symbols for laser energy and laser cooling devices (when necessary) in the laser model composition method. This standard replaces and abolishes Appendix A of GB/T4799-1984 and GJB/Z43.2-1993 from the date of implementation. This standard is proposed and managed by the Ministry of Information Industry. The drafting unit of this standard: China Electronics Technology Standardization Institute. The main drafters of this standard: Ma Tianqing and Hui Jiabao. The gas laser model naming method in this standard was first released in December 1984 (GB/T4799-1984); the solid laser model naming method in this standard was first released in December 1993 (GJB/Z43.2-1993 Appendix A). This standard is entrusted to China Electronics Technology Standardization Institute for interpretation. I
