Foreword
This standard is drafted in accordance with the rules given in GB/T 1.1-2009.
This standard replaces GB/T 11297.1-2002 "Measurement method of laser beam wavefront distortion". Compared with GB/T 11297.1-2002,
In addition to editorial changes to the main technical content changes are as follows.
--- modified test conditions (see 4.1,.2002 version 4.1);
--- modified the side of the measured laser rod parallelism requirements (see 4.2,.2002 version of 4.4);
- modified test equipment and requirements (see Chapter 6, 4.3 of.2002);
- Increased measurement accuracy requirements (see Chapter 8).
This standard is proposed by the Ministry of Industry and Information Technology.
This standard is owned by the Ministry of Industry and Information Technology (electronic) of the People's Republic of China.

Measurement of wavefront distortion of laser rods
1 Scope
This standard specifies the measurement conditions and test procedures for calculating the wavefront distortion of the material itself using the phase shift interferometry.
This standard applies to the wavelength of 633nm light wave can pass through the laser crystal, also applies to glass, ceramics or other similar materials.

Terminology for solid - state lasers
3 terms and definitions
GB/T 11293-1989 Definitions and the following terms and definitions apply to this document.
3.1
Wavefront wavefront
The same phase of the light wave vibrates the phase.
3.2
Wavefront distortion wavefrontdistortion
When the ideal light (plane wave or spherical wave) is transmitted or reflected, the wavefront changes occur as wavefront distortion, usually with the largest distortion
(PV) as its digital indicator.
4 requirements
4.1 Test conditions
Unless otherwise specified, the test shall be carried out under the following conditions.
a) Temperature. 22 ° C ± 5 ° C;
b) Temperature fluctuation during test. ≤ 1 ℃;
c) relative humidity. ≤85%;
d) should be in the absence of vibration, air, dust environment.
4.2 measured laser bar requirements
In addition to special requirements, the laser rod should meet the following requirements.
a) Both sides of the parallelism (plane/plane) should be better than or equal to 30 ";
b) the vertical distance of the end face to the shaft should be better than or equal to 5 ';
c) the diameter of the face pits φ0.004mm ~ φ0.1mm, the total number of less than 0.8D0, scratches width 0.004mm ~ 0.1mm, total length
Degrees less than 2D0 [D0 for the diameter of the laser rod, in millimeters (mm)];
d) The end face should be clean, without affecting the measured dust and light stains.
