Laser Diode Applications

Course Details Field of Study: Electronics Engineering Course Name: Optoelectronics Subtitle: Laser Diode Applications According to the material used to form the p-n junction the laser diodes are classified. Different laser diodes got different applications. GalnAsP This is a diode made up of Ga,ln,As and P. which emits laser light having wavelength 1300nm. It find

Operation of laser diode

Course Details Field of Study: Electronics Engineering Course Name: Optoelectronics Subtitle: Operation of laser diode When a p-n junction is forward biased by an external voltage source, the electrons move through the junction and recombines as in an ordinary diode. When electrons recombine with holes, photons are released. These photons strikes atoms, causing more photon

Basics of a complete laser system

Course Details Field of Study: Electronics Engineering Course Name: Optoelectronics Subtitle: Basics of a complete laser system The gain medium is pumped by some method. Some of the atoms/molecules are excited. Spontaneous emission occurs, in all directions. Emission along long axis of cavity is reflected back through the gain medium. The spontaneously emitted photons stimulate

Laser Gain

Course Details Field of Study: Electronics Engineering Course Name: Optoelectronics Subtitle: Laser Gain The amount of amplification of the incident beam in a single pass is small, a fraction of a percent/centimeter of travel. To increase the path length through the sample could use either: • A very long laser/gain medium. • Mirrors to reflect
