Outline of Final Research Achievements

I developed simulation code for designing solar cavity to realize effective absorption of solar energy into laser medium with less thermal effect. The code is based on ray-tracing and the calculation model include a Fresnel lens of the 1st concentrator. The code has a function of non-linear optimization for designing the shape of the solar cavity with maximum absorption efficiency and minimum thermal effect.
Considering the simulation results, I developed new solar-pumped laser system which is smaller than previous one to reduce thermal effect inside laser medium and laser cavity.
