Patent ID: 7113526

Claim:
A surface emitting semiconductor laser system, comprising: a first cavity having a first reflector at a first end and a second reflector at a second end; a second cavity having a third reflector at a first end and a fourth reflector at a second end; a third cavity having a fifth reflector at a first end and a sixth reflector at a second end; a fourth cavity having a seventh reflector at a first end and an eighth reflector at a second end; wherein the second reflector is reflective of a first wavelength of light but transmissive of a second wavelength of light; wherein the fourth reflector is reflective of the second wavelength but transmissive of the first wavelength; wherein the sixth reflector is reflective of a third wavelength of light but transmissive of a fourth wavelength of light; wherein the eighth reflector is reflective of the fourth wavelength but transmissive of light the third wavelength.
