Abstract
Laser display has been attractive because extremely wide color expression can be realized by choosing the wavelength of laser sources. The highly efficiency and small etendue of laser sources contribute to downsizing, and long lifetime is also another merit for users. High power and compact red, green, and blue (RGB) lasers have been expected to realize the practical laser display. In this paper, highly efficient RGB lasers based on laser diodes and second harmonic generation devices are introduced. Also laser display systems by using these lasers are discussed.
