We report on progress in development of the low-cost, highly efficient miniature diode-pumped solid-state (DPSS) green laser sources for pico-projectors and other consumer electronics applications with wavelength 532 nm. As Spectralus laser has monolithic microchip structure there are other green lasers with various discrete designs. We are reviewing both approaches in this paper.

Key words: mobile projector, pico projector, green laser, microchip laser, low noise laser, periodically poled lithium niobate, periodically poled magnesium oxide lithium niobate, PPLN, PPMgOLN, second harmonic generation, intracavity second harmonic generation
