Outline of R&D Project

In the CREST project, it was demonstrated that photonic crystal surface-emitting semiconductor lasers (PCSELs) can achieve a perfect single mode oscillation in a broad area. By maximizing this advantage, we aim at developing lasers with a stable, high power and high brightness operation that can lead to it being applied to laser processing, which could not be achieved with existing semiconductor lasers. We will also develop various functional lasers that can be utilized for various potential applications in biology, precise measurements, and so on.
