Diode Laser Lab Anthony Mannino Lab Partners: Adam Keegan, Chris Dahdouh Abstract: The purpose of the following four experiments were to observe the properties of the 808 nm diode laser using such equipment as a function generator, an oscilloscope, and the Nd:YAG material . umerous applications in the world today. These include the medical and scientific fields for processe such as laser spectroscopy and surgery. A Nd:YAG laser can be optically pumped using lasers of several different wavelengths. Diode lasers have been called “wonderful little devices. The laser operation occurs at a p-n junction that is the boundary region. In this experiment, you will learn the characteristics and the operation of one of the most commonly used and increasingly popular lasers (Light Amplification by Stimulated Emission of Radiation) in chemical instruments: a semiconductor laser. 650nm laser diode and mount, collimating lens mounted on translation stage, injection current circuitry box, 9V DC transformer, DC power supply (Unilab), two multimeters, optical power meter. The device consists of one meter long optical bench with two transversal saddles for laser and slit mount and one transversal saddle with micrometer for detector.
