Patent ID: 7173775

Claim:
A system for mixing a plurality of independent Gaussian profile light beams of different wavelengths to form a single homogenous output light beam, comprising: a first homogenizer tube having a hexagonal cross-sectional shape for receiving a first Gaussian profile light beam having a first frequency; and a second homogenizer tube having a hexagonal cross-sectional shape for receiving a second Gaussian profile light beam having a second frequency, said second homogenizer tube including an optical element at a second end thereof opposite to a first end, wherein the first end receives said second Gaussian profile light beam; said optical element having a first surface that is reflective for receiving and reflecting said second Gaussian profile light beam, toward an output end of said first homogenizer tube; and said optical element having a second surface that is transmissive to pass said first Gaussian profile light beam so that said first and second Gaussian light beams mix at said output end of said first homogenizer tube to form a homogeneous output signal beam having a third frequency.
