Green Laser Market for Projection Devices


Green Laser Market for Projection Devices

The green laser market today is highly segmented in numerous niche applications from medical to military applications and laser shows. Those applications can work with existing Solid State Lasers or the more recent combinations of semiconductor lasers with non linear crystals (SHG: Second Harmonic Generation).
In the emerging market of pico-projectors and other display techniques such as Head Mounted Display (HMD) or Head up Display (HUD), the ideal light emitting device would be lasers thanks to their capability to deliver highly saturated colors in the widest possible gamut. Additional features are focus-free operation and expected improved wall-plug efficiency which will affect the power consumption for battery operation.
In 2009 however, the first LED based picoprojectors have been available on the marketplace with a slow take-off. No more than 300k units have been sold. The poor brightness (10 lm) for a relative high price might be a reason for this.
In the same year some impressive progress has been published on the capability to shift the blue laser diodes towards the green wavelength. The direct-emission semiconductor laser should be available in the coming years (2011-2012) to serve the projection display applications.
This report provides a complete analysis of the projection applications targeted by the green laser diodes along with key market metrics. It describes the involvement of the major laser device manufacturers and gives a snapshot of the GaN material industry playground. The report presents the $ and unit values on the 2009-2016 time scale for the green laser diode devices and the related material market size in 2” equivalent.
