The FRLD-785-500-FS-VBG-BTF from FrankFurt Laser Company is a Free Space Laser Diode that operates at a wavelength of 785 nm. This laser diode delivers a minimum continuous wave power of 500 mW and has a maximum spectral width of 0.1 nm (at FWHM) with a slope efficiency of 0.7 W/A. It requires a threshold current of 0.4 A, a DC supply of 2 V, and consumes 1.1 A of current. This laser diode has an inbuilt photodiode that consumes a maximum current of 2000 µA, a maximum TEC current of 2.5 A, and requires a maximum TEC voltage of 6.3 V. It is available in a 14-pin solid butterfly package that measures 38.1 x 30 x 8.1 mm and is ideal for Raman spectroscopy, scientific research, analysis, and medical applications.
