Laser Rough Adjustment

Determine the position of the argon laser by using the optical axis of the farthest He-Ne laser (He-Ne1 laser in
Figure 5.2-3 or in Figure 5.2-4) as the reference. Align the lasers so that their laser beams can be transmitted
through the optical fiber for the excitation light.
