Semiconductor Injection Diode Laser
Abstract/Description: | Early Semiconductor Injection Diode Laser - newest laser is a tiny semiconductor crystal shown here suspended inside a glass container filled with liquid nitrogen, which helps keep the device cool when large amounts of electric current are passed through a junction in the crystal to generate a beam of coherent infrared light. Preparing the revolutionary type of laser for operation is Dr. Hall of General Electric Research and Development Center, discoverer of what has been described as 'the simplest, most compact, most efficient, and most direct method yet discovered for producing laser action.' In the reflecting prism below the glass container, the laser crystal can be seen as a small spot between to connecting electrodes. |
