| Outline of Final Research Achievements |
Recently, many kind of renewable energy has been studied including solar power. In this study, we focused on the solar-pumped laser as a means to obtain storage-type energy from sunlight. We attempted to improve the efficiency of generation of bio-ethanol by using an ultraviolet laser to the pre-treatment of the woody biomass.
New laser crystals that absorb sunlight at a high efficiency were successfully grown. We have succeeded in increasing the amount of absorbed energy to more than 70 times that of conventional crystals.
Furthermore, by utilizing the solar-pumped laser to the pretreatment of woody biomass, we are aiming to establish a method to improve the production efficiency. We attempted preliminary experiment of biomass fuels production using the laser. In the experiment, pulsed UV laser was irradiated to the powder of xylem. As the result, about 30% increase of production efficiency of ethanol was demonstrated.
