A laser diode, also known as a diode laser, is a semiconductor device that emits light radiation which is coherent. Laser diodes generate a beam of high intensity light and are also referred to as injection lasers.
Though laser diodes are similar to the light emitting devices (LED), they are different from the other types of lasers, such as Helium-Neon and gas lasers. The weight of laser diodes is typically a fraction of a gram, therefore, they are suitable to be used in portable electronic equipments. Furthermore, the power requirements of laser diodes are very less as compared to the conventional lasers. As the laser diodes consume less power, they can operate even when there is a very little battery power supply. You can also easily switch the laser diodes on and off at high frequencies, due to which laser diodes can be used in high-speed telecommunication applications. Since laser diodes are small in size and made of semiconductor materials, they can be easily used in places where other types of lasers cannot be used.
Due to their continual advancement and developments, laser diodes are today available in shorter wavelengths and can produce an increased output power. Following are some of the different types of laser diodes available:
From data recording and storage to optical fiber communications, high-speed telecommunication, dermatological therapies to remote optical sensing and blood analysis, laser diodes are today used across a wide range of industries.
Considering the wide range of areas that laser diodes can be used in, the study of laser diodes is a sought after course these days. MIT Academy of Engineering is one of the best engineering colleges Pune that offers the course for the study of laser diodes. MIT is a trusted name when it comes to imparting education. You can browse through the full range of undergraduate and postgraduate courses that MIT offers and select a desired one. The training and placement cell at MIT provides the much needed guidance and counseling to the students and boasts of a good placement record. Moreover, here you could also find information on postgraduate opportunities and scholarships being provided by a lot of universities abroad.

1. Surface emitting laser diode: In this kind of laser diode, light emits in a direction that is perpendicular to the wafer surface of the semiconductor chip. This is a new type of laser diode.
2. High power laser diode: It produces a high intensity power beam and is pretty small in size. The power requirements of high power laser diodes are very less.
3. Index guided laser diode: It reduces astigmatism in single-mode output beams that it generates.
4. Gain guided laser: It is the simplest kind of laser diode which uses a mechanism to control the spread of the laser beam.
