On January 29, 2020, Panasonic Corporation announced it has succeeded in demonstrating the world's highest brightness blue laser. This has been achieved by using the wavelength beam combining (WBC) technology [1] on a direct diode laser (DDL) to produce a high quality output beam [2]. With this technology, power scaling is enabled while maintaining the beam quality by simply increasing the number of laser sources. This demonstration opens the door to laser intensities that could be two orders of...
