nLIGHT continues to drive innovation in multi-emitter diode modules, as demonstrated by successfully reducing our laser diode voltage by means of a revised epitaxy across multiple wavelengths, and then demonstrating module level results of these new devices by successfully productizing 465 W with a beam NA of 0.16 at 920 nm, in a 24-emitters module with 200 µm fiber, and also achieving 265 W at 53% efficiency with VBG stabilized 885 nm devices in 24-emitter module coupled into 200 µm fiber, all while measuring an extremely broad locking range.
