摘要
介绍了半内腔式He-Ne激光器的结构及调整的技巧,测量了在不同放电电流以及不同腔长条件下激光器的输出功率,得到了最佳的放电电流.半内腔式He-Ne激光器的应用,有助于学生了解激光器的工作物质、谐振腔等主要组成部分,也促进了学生对激光理论的进一步理解.
The structure and adiustment technique for semi-internal cavity He-Ne laser are introduced, and the output power is measured under the conditions of different current and cavity length. Due to the application of semi-internal cavity He-Ne laser, the main structure such as work material and optical resonator can be observed directly and the laser theory is more easily understood for students.
