Laser-Tv the next television generation?

Lasers may become an ideal replacement for the UHP lamps, which are currently in use in projection display devices such as rear projection TV and front projectors. Current televisions are capable of displaying only half of the visible spectrum of colors.

A laser TV requires lasers in three distinct wavelengths: Red, Green and Blue. While red laser diodes are commercially available, there are no commercially available green and blue laser diodes which can provide the required power at room temperature with an adequate life time. Instead frequency doubling can be used to provide the blue and green wavelengths. Several types of lasers can be used as the frequency doubled sources: fiber lasers, inter cavity doubled lasers, external cavity doubled lasers, eVCSEL's and OPSL's (Optically Pumped Semiconductor Lasers). Among the inter cavity doubled lasers VCSEL's have shown much promise and potential to be the basis for a mass produced frequency doubled laser.
