[PL-02 (Plenary)]GaN-based Laser Diodes and Their New Applications
〇Shin-ichi Nagahama1(1.Principal Researcher, General manager LD Development Dept. NICHA Corporation, Japan)
Biography
Visible light Laser Diodes (LDs) have many features that other light sources do not have, such as wide color reproduction range, small size, robustness, long lifetime, low power consumption, and small etendue. Recently, in GaN-based LDs, Green LDs have been mass-produced in addition to Blue LDs. By adding existing AlGaInP-based red LDs to these, RBG LDs are now available. As a result, laser displays that use LDs as the light source for laser TVs and laser projectors have been commercialized more and more.
Currently, laser displays using visible light LDs are growing in the market. In addition to consumer applications, visible light LDs are also being used in new applications such as vehicles, lighting, and industrial applications such as laser processing. In this presentation, we will report on our history and current status of the development of GaN-based LDs and outline their new applications.
