Patent attributes
A light source device including: a first light source configured to coaxially combine a plurality of first laser beams, each having a peak wavelength within a first wavelength range, to thereby generate and emit a first wavelength-combined beam; a second light source configured to coaxially combine a plurality of second laser beams, each having a peak wavelength within a second wavelength range that defines a range of peak wavelengths shorter than the peak wavelengths in the first wavelength range, to thereby generate and emit a second wavelength-combined beam; and a wavelength filter configured to coaxially combine the first wavelength-combined beam and the second wavelength-combined beam to thereby generate and emit a third wavelength-combined beam.
