Influence of focal length of convex lens on the intensity of spot size of Helium-Neon laser is demonstrated experimentally. Intensity of spot size reduces with the enhancement in the focal length of convex lens. For convex lens of focal length 21 cm, intensity of spot size approaches to its peak value.
