Abstract
A 12-W green laser diode module with fiber-coupled output is developed. The high-power fiber-coupled output of a green diode laser is realized by using the technologies of beam collimation, spatial beam combining, beam shaping, and fiber coupling based on TO-Can packaged emitters. According to the optical fiber parameters, the detailed beam combination method is described and the maximum quantity of a single emitter in beam combination is calculated theoretically. In the experiment, as many as 16 green laser diode emitters with output power of 1 W each were combined and coupled into a fiber with core diameter of 200 μm and a numerical aperture of 0.22. A total of 12.2 W continuous-wave output at the wavelength of 520 nm was achieved with a coupling efficiency of 86.5% and an electro-optical efficiency of 10.6%.
