Abstract
This paper presents a low cost semiconductor red laser light delivery system for esophagus cancer treatment. The system is small enough to slide inside the patient"s body and it produces up to 4 Watts of optical power from several semiconductor lasers. Specifically, the paper presents optimized high power 635 nm semiconductor laser array design with testing results. The laser array is more powerful than conventional ridge waveguide and more reliable than the broad area lasers at this wavelength. The design optimization is based on i) thermal analysis using finite element analysis as well as analytical calculations for minimizing laser array temperature, and ii) specially designed scattering elements with nanoparticles, to achieve uniform illumination.
