In recent years, visible semiconductor laser diodes (LDs) have been used in a variety of applications. After that, GaN-based LDs have been investigated and blue and green LDs were developed. In particular, progress has been made recently in improving the characteristics of GaN-based high-power blue-violet, blue, and green LDs. This paper introduces improvements of a GaN-based high-power LDs and an example of its development into new application fields.
