Claim Text:
1. A light source apparatus, comprising: a first laser light source arranged to output a first white laser light beam with a first polarization; a second laser light source arranged to output a second white laser light beam with a second polarization; wherein the polarization of said second white laser light beam is orthogonal to the polarization of said first white laser light beam; and a multi narrow-band polarizing beam splitter positioned to receive said first white laser light beam and said second white laser light beam for combining said first and second polarizations; wherein said multi narrow-band polarizing beam splitter has a half cone acceptance angle smaller than or equal to 5°; wherein said multi narrow-band polarizing beam splitter is optimized for three separate narrow spectral ranges, whereby said ranges comprising a width up to 30 nm.
