A laser diode is an electrically pumped system which is formed by the p-n junction of a semiconductor diode, similar to an LED. Laser diodes have become an indispensable part of the modern technology due to their extensive use in applications such as laser printers, CD players, industrial processing machineries, research and development, and laser pointers. Laser diodes offer significant advantages over other conventionally used lasers such as helium-neon, ruby, and gas. These advantages include:
- Small weight and size
- Low current, voltage, and power requirements
- Wide angle beam
- High electrical efficiency
- Low maintenance
Use in Factory Automation, Communication, and Display Boosts Demand for Laser Diode
Laser diodes are used for material processing, data storage, communication, sensing and display, and factory automation, thus fueling their demand. The growth of the end use markets of laser diodes directly benefits the laser diode market. The demand for high speed internet services such as cloud services, 3G, and long term evaluation (LTE) are expected to increase. This increase will lead to a surge in the demand for laser diodes. These diodes are extensively used by telecommunication companies to transmit data as they consume lesser amount of power compared to other modes of transmission. The application of laser diodes are expected to emerge in the field of space communication and optical radar equipment. This will further their demand.
Dependency on Temperature Impedes Market’s Growth
Laser diode output is greatly dependent on temperature and hence, any increase in the temperature results in high power loss. The laser technology can be used for various processes such as marking, cutting, drilling, and other industrial processes. However, high initial costs associated with these machines is posing as a challenge for the growth of laser diode market.
