Describes the overall light path layout and commissioning of the neodymium glass laser Thomson scattering system on the HL 1M device and the measurement of the electron temperature on the HL 1M device. The scattered light source is a neodymium glass laser with one stage of amplification and producing 1 or 8 laser pulses, which produces a pulse with a wavelength of 530 nm and an output power of about 10 MW after doubling with a nonlinear KDP crystal. The use of a large aperture receiver optical path and Df = 128.8 grating spectrometer enables the measurement of the electron temperature at five points in the plasma. The line dispersion is about 4 2nm · mm-1, the temperature measurement range of 10 0eV ~ 2keV.
