Serial Experiments of He-Ne Laser

Description

Through the adjustment of the He-Ne laser, the length of the resonant cavity is changed, the change of the laser mode is observed and the practical ability of the students is trained. The confocal spherical scanning interferometer is used to allow students to measure the divergence angle of the He-Ne laser. The spectral distribution of the transverse and longitudinal modes is observed directly.
