Abstract
The principles, techniques and apparatus of two demonstration experiments using a tunable cw-laser are described. In the first experiment a passive external cavity enhanced the intensity of an incident laser beam enough to generate easily detected second harmonic UV radiation. The experiment also showed how to lock the frequency of one cavity to that of another. The second experiment used laser saturation spectroscopy to obtain sub-Doppler resolution and thereby exhibit the hyperfine spectrum of iodine molecules.
