Foreword

This standard rule according to GB/T 1.1-2009 given draft. This standard replaces GB/T 15175-1994 "solid-state lasers main parameters of the test method." This standard and GB/T 15175-1994 compared to the main changes are as follows. --- Quoted in Chapter 3 GB/T 15313, delete the original standard and GB/T 15313 the same content of terms and definitions; --- Chapter 4 adds provisions "arbitration measure atmospheric conditions"; --- Delete the original standard "transverse mode mode" measuring method (see 1994 edition 5.3); --- In the "beam width or beam diameter" measurement method increases the measurement "hollow probe method" (see 5.7); --- Increase "beam quality" measurement methods (see 5.9); --- States that the "degree of polarization" specific content measurement method, delete the original standard GB/T 7257 "helium-neon laser parameters tested party Law "reference (see 5.11); --- Added Appendix A, Appendix B and Appendix C. The standard proposed by the Ministry of Industry and Information Technology of the People's Republic of China. The standard by the China Electronics Standardization Institute. This standard was drafted. China Electronics Standardization Institute. The main drafters. Zhang Peng, Chen Lan. This standard replaces the standards previously issued as follows. --- GB/T 15175-1994. The main parameters of solid-state laser measurement method
