A semiconductor laser is an electrically-pumped system wherein the active medium is formed by the p-n junction of a semiconductor diode, similar to that found in a LED. Laser diodes are rapidly becoming an indispensible part of modern technology and are being used in applications such as CD players, communications, laser printers, industrial processing machineries, laser pointers, and research & development. Laser diodes offer several advantageous features over the conventional laser systems such as solid state lasers and gas lasers, because of their small size and weight, low voltage, current and power requirements, high electrical efficiency and low maintenance and wide-angle beam. These advantages of semiconductor lasers are expanding its applications in medical, consumer electronics and other growing sectors. Low output of semiconductor lasers is limiting its adopting in high power applications such deep space communication and industrial applications. However, continuous development in designing and materials to improve the output power of semiconductor lasers is expected to help manufacturers to overcome this challenge in the near future.
There are different types of semiconductor lasers include fiber optic lasers, compact disc lasers, high power diode lasers, vertical cavity surface emitting lasers, red lasers, violet lasers, green lasers and blue lasers. Fiber optic lasers are used in communication application and accounted for the largest market share in the global semiconductor laser market. This segment is expected to see a steady growth through the forecast period with growing demand for high broadband services and its growing acceptance in marine and space communication. High power diode lasers are expected to observe the fastest growth through the forecast period 2014 – 2019, with its growing applications for material processing, solid-state laser pumping, fiber laser pumping, solid state laser pumping, space communication, defense and optoelectronics manufacturing. Blue lasers, violet and green lasers are rapidly replacing red lasers in many applications such printing, optical storage devices and defense due to their high efficiency and high brightness.
