2019 Emitting Green Laser Diode
Indium gallium nitride (InGaN) laser diodes can directly produce laser diodes that emit blue light, but it is difficult to produce laser diodes that emit green light directly, especially those that are considered to be truly green: early green laser diodes Usually has a slight cyan projection. As a commercial pioneer of green InGaN laser diodes, OSRAM Opto Semiconductors has been promoting the development of long-wavelength laser diodes. A laser based on InGaN-based direct-emitting green light has been introduced, with wavelengths from 510 to 530 nm, which can be used for micro-projection. And other red, green, blue (RGB) or green laser applications. (Osram also produces blue laser diodes.) The new lasers are available in TO38 ICut or TO56 packages (with a flange diameter of only 3.8 mm) with integrated photodiodes, typically with a parallel divergence angle of 7°and a vertical divergence angle of 22°, small enough to pass The relatively simple optics are cyclized and collimate...
