[SLPC4-02(Invited)] Recent Progress of PCSELs for Laser Processing

*Susumu Noda¹ (1. Kyoto University)

Photonics-crystal surface-emitting lasers (PCSELs) are a new type of laser that possesses both high power and high beam quality, namely, high brightness, while maintaining the merits (compactness, high efficiency, and high controllability) of semiconductor lasers. In this plenary talk, I will discuss the recent progress of PCSELs and their application to laser processing.
