    Abstract: The present invention provides a light source apparatus (10) for use with a projector (80) and a method for combining laser beams of different polarization characterized in that an overall efficiency for the reflection and transmission exceeding 97% is achieved. A first white laser light beam (18) having a first polarization is combined with a second white laser light beam (28) having a second polarization that is orthogonal to the first polarization by utilizing a multi narrow-band polarizing beam splitter (20) positioned to receive the first and the second white laser light beams (18, 28). Embodiments of the present invention utilize two laser light sources (12, 22) emitting two sets of laser light beams with multiple wavelengths (14, 15, 16 and 24, 25, 26).
