-
A thermal stabilization technique for multimode He-Ne laser tubes is demonstrated. Intensity stability of ∼1% is achieved, where the intensity of the unstabilized laser varied by more than a factor of 5. The system provides both a dramatic demonstration of the principle of negative feedback and a stimulating introduction to basic electronics, laser physics, and solid state physics. It is simple ... read moreenough to be constructed as an undergraduate laboratory project.read less
