1. If the frequency of light from a laser was to be halved, what physical changes would have to be made to the laser?
2. Describe the basic process of laser cutting.
3. What is the major limiting factors for depth of cuts using lasers?
ans. The diffusion of the beam, and distortion due to gases limit laser depth to a reasonable range of about one inch.
4. We are to make a cut, that is 1/4in thick and 10in long, using a laser. If the laser kerf (cutting slot) is 1/16in wide, what is the cutting time?
