YL-I-638/525/450/808/1064638 nm red high-power multi-wavelength laser
638 nmThe YL-I-638/525/450/808/1064 is a 638 nm direct diode laser. Electrical current creates optical gain in a semiconductor junction, and the diode generates the laser light directly. Optical feedback selects the oscillating modes, while drive current and junction temperature affect output power and wavelength. The specified fiber connection delivers the generated light to the experiment; its core size, numerical aperture and connector need to match the receiving optics.
