Highly‐efficient fully air‐cooled green laser light source with frequency doubling module is reported. As a result, 3.6 watts green laser light generation with about 9% wall‐plug efficiency is achieved. By using fully air‐cooled RGB lasers including the green SHG (Second Harmonic Generation) laser and illumination optics for speckle noise reduction, a laser projection engine is prototyped. A laser rear‐projection system with this laser projection engine shows several merits; wide color gamut (133%NTSC), 61inch large screen size, and low electric power consumption (less than 100W, at 650cd/m 2 ).
