Abstract: The principle of the grating tuning is introduced, the performance of the blazed grating is analyzed
and the grating parameters are selected. The system of the grating tuning line selection of TEA CO2 laser is de⁃
signed, the hardware and software of the tuning line selection output control system are developed. The experi⁃
ment shows that the system of the grating tuning line selection of TEA CO2 laser can accurately and fast realize
the output of the grating line selection.
Key words: TEA CO2 laser;grating tuning; blazed grating; infrared zero position sensor
