摘要
可调谐激光原理实验仪,是以N_2激光器作泵浦源,以有机染料作激光物质,以光栅与输出反射镜作谐振腔组装的。让学生亲自动手组装、调试实验仪,做激光原理实验,可以使学生切实地体会到:实现粒子数反转就可能产生激光,满足阈值条件就有稳定的激光输出,否则就不能产生激光,不能有稳定的激光输出;还明确了在结构上如何组装、调试才能确保激光的稳定输出。
The Dye Tunable Laser Principle Instriument consits of a N_2 Laser, organic dye, and both a grate and output-mirror. Where the N_2 Laser is used as pump source, the organic dye as Laser material, and both a grate and output-mirror as a resonart cavity. The students will be allowed to install and adjust the instrument and do this experiment by themself, so the students can understand realisticly that if the population inversion has been achieved, the Laser may be producted, and that if the threshold condition has been satisfied, there is the steady Laser output. Otherwise the Laser can not be producted and there is not steady Laser output. Also, the students can know how constitute and adjust the instrument to generate Laser and to obtain the steady output of Laser.
