The global green laser diode market is expected to witness significant growth over the next six years owing to their inherent favorable characteristics such as small size & weight, low voltage, current & power requirements, high electrical efficiency, and low maintenance. Need for high flexibility, greater production speed, reduced part costs, and higher reliability, are some of the key drivers for the green laser diode market. Government regulations directing mandatory laser technology use in engraving and marking products are expected to favorably impact market growth.
Green laser diodes have profound applications in Heads-Up Display (HUD), Head-Mounted Display (HMD), pico-projectors, and smartphones owing to their capability of delivering a wide range of highly saturated colors and focus-free operation. These diodes have also been increasingly incorporated in several applications in medical, semiconductor, instrumentation, and military sectors. Ability to operate in a wide range of temperatures of over 60°C (140°F) without the need for cooling has significantly enhanced green laser diodes’ utility. The laser typically operates at 2V and its wavelength can be modulated at frequencies higher than 500 MHz.
Growing environmental concerns pertaining to rare earth elements’ mining and high initial costs involved in the purchase of laser processing machines are expected to hamper green laser diode market growth over the forecast period. Some of the doping materials used in green laser diodes’ production include AlGaInP, GaAlAs, GaInAsSb, GaN, and InGaN. AlGaInP-based laser diodes are used in several applications including data communications, DVD players, laser pointers, and optical discs.
OSRAM, Sumitomo, Coherent, IPG, Sharp Corporation, and SPI are some of the major players in the green laser diode market.
