Laser diodes are electrically pumped semiconductor lasers and are different from the optically pumped lasers found commonly. These laser diodes use different semiconductor materials for doping based on the wavelength needed and end use application.
The current market for diode laser is an impressive $4.11bn, as of 2013, but it is predicted that the market will grow to a stable $5.67bn by 2019. The global market for diode laser in the last decade has proven to be highly volatile with flat growth, revenue dips and growths seen by the industry players. However, the industry has proven itself to be quite resilient, as the products manufactured by more than 50 players across the world are used in key industry verticals, like telecommunications and medical segment. The growth prospects of new and emerging product segments, like high powered direct diode lasers, green diode lasers, and other such extremely pertinent products will add to the scope of growth for this market.
Diode lasers are primarily semiconductor lasers based on laser diodes. Although the terms diode laser and laser diode are often used interchangeably, the diode laser is a laser device, consisting mostly of a single laser diode, but may also contain additional items like an external optical resonator in the case of an external cavity diode laser. They may also include additional optics outside the laser resonator, such as a beam collimator or a beam shaper, like in the case of a fiber-coupled diode lasers. Diode lasers essentially contain photonic materials which convert electric current into laser light and have a maximum efficiency of around 70%. The wavelength of the light in which such diode lasers operate ranges from 400nm to 1500nm. All modern lasers use the double-hetero-structure implementation, unlike the general earlier laser diodes which were simple P-N diodes.

Globally, laser applications are used primarily for signal transmission that include fiber optics, optical data storage – CD and DVD-R, directed energy – materials processing and welding, sensing, pollution monitoring, analysis, and other such work. The diode lasers which are deemed important are optical fiber systems, free space optics, Bragg gratings, distributed feedback lasers, distributed Bragg lasers, external cavity lasers, Fabry-Perot lasers, quantum cascade lasers, fiber amplifier lasers, tunable lasers, VCSELs, microchip diode lasers, violet diode lasers, laser pointers, CD diode lasers, DVD diode lasers, Erbium-doped fiber amplifiers and Raman lasers. A significant number of players occupy the market, and the drive is now towards making laser technology more versatile and affordable.
IndustryARC expects the overall market for diode laser to increase from around $4.35bn in 2014 to around $5.67bn in 2019, growing at a rate of 5.44% during the forecast period. The presence of new market opportunities, the reduction in product ASPs, innovative and power efficient product launches from many companies are considered to be extremely pertinent for the growth of this market. Entertainment, materials processing like laser blazing, polymer or thermoplastic welding, instrumentation are some of the major end user application segments, where diode lasers are expected to showcase their fastest growth rates. However, traditional high growth segment, like optical storage and printing as well as scanning, are expected to show flat or slow growth rates during the forecast period because of the technological shifts and declining product demand.
