Growing pico-projector market demands RGB light engine based products with higher brightness and longer battery life.? Laser-based pico-projectors can meet both requirements. Blue and red semiconductor direct lasers with wavelengths of 445nm and 640nm are available from a number of vendors.? At the same time direct green diode lasers that are available now still lack efficiency and output power required for the efficient projectors with high brightness of more than 20 lumens.? In RGB light source, a green laser is the major lumen provider, therefore development and production of compact, efficient, low cost and high power green laser is critical for commercialization of laser picoprojectors.
We discuss progress in development of the low-cost, highly efficient miniature diodepumped solid-state (DPSS) green laser sources for pico-projectors and other consumer electronics applications with wavelength 532nm.
