This document introduces the construction and working principle of the He-Ne laser power supply, including the installation, debugging, and ignition process of the power supply. It also discusses the excitation method of gas lasers and the technical parameters of He-Ne laser tubes.
The document introduces the working principle of a He‑Ne laser power supply and provides detailed instructions for assembling the circuit board, connecting the laser tube, and adjusting the operating current. It also lists typical technical parameters for various He‑Ne tubes.
Safety guidelines are included, emphasizing the need to avoid direct eye exposure to the laser beam, to disconnect power before handling, and to use proper short‑circuiting methods when servicing the unit. This manual is written in Chinese.
It aims to help the reader understand the He‑Ne laser power supply principle, complete its installation, and safely ignite the laser tube.
Never look directly at the laser, disconnect power before handling, use a short‑circuit bag after power‑off, and avoid touching the tube electrodes.
