Foreword

This standard was drafted in accordance with GB/T 1.1-2009 given rules.

This standard replaces GB/T 13863-1992 "laser radiation power testing methods" and GB/T 13864-1992 "laser radiation power stability Set of test methods. " Compared with GB/T 13863-1992, in addition to editorial changes, the major technical changes are as follows.

--- Modify the terms and definitions (see Chapter 3, Section 3 of the 1992 edition);

--- Modify the test conditions and requirements (see Chapter 4, 1992 edition, Chapter 4);

--- Increased large divergence angle of the laser radiation continuous power test (see 5.1.1.2);

--- Added optional test equipment (see 5.1.4);

--- Increase in measurement uncertainty estimation (see Chapter 6);

--- Increasing the content of the test report (see Chapter 7).

3 Terms and Definitions

GB/T 15313 and defined by the following terms and definitions are applicable to this document.

Continuous peak laser output power instability relativepowerpeakfluctuationoflaserradiation deltaP2 Within the sampling period corresponding to the laser power 1Hz or less continuous ups and downs amount to half of the peak laser power than the continuous, Peak laser output power instability see equation (1).

deltaP2 = ± Pmax-Pmin2P × 100% (1) where.

Pmax --- corresponds to the maximum sampling period of continuous laser power measurement value, in units of watts (W);

Pmin --- corresponds to the minimum sampling period of continuous laser power measurement value, in units of watts (W);

P --- sampling within the corresponding period of continuous laser power measurement value of the average, in watts (W).
