He-Ne Laser and Laser ResonanceF-HX1020 for electricty instrument

1,Use a half intercavity He-Ne laser to satisfy laser starting for producting laser. 2,Measure laser gain in the intracavity.

F-HX1020  He-Ne Laser and Laser Resonance

Experiment contents and related subjects:

1. Using semiconductor laser as the collimation light source and self-collimation method to adjust a semi-internal cavity He-Ne laser to meet the staring conditions for oscillation and so as to produce laser.

2. By moving the reflecting mirror on the guide to change the resonant cavity length, the relationship between cavity length and the transverse mode, longitudinal mode (with F-P scanning interferometer), power can be observed and, at the same time, the effect on waist diameter and divergence angle can also be observed. The working principle of laser and laser resonate theory can be understand and grasped.

3. Measure the gain of the laser by inserting an adjustable loss in the cavity.

4.Laser beam analyzer which can observe the spot intensity distribution, measure spot diameter and divergence angle, etc. (optional)  

Complete set of equipment:  

Optical experiment guide, semiconductor laser, semi-internal cavity He-Ne laser, beam expander mirror, two-dimensional adjustable mold piece frame, laser power indicator, gain measuring annex, F-P scanning interferometer (optional), laser beam analysis meter (optional), oscilloscope (self) and etc.
