High power diode laser source with wavelength coupling technology
Laser diode has incited particular interest as photoelectric conversion efficiency,output power and lift time for a variety of applications in industry processing.The single laser diode optical power has not satisfied for the actual requirements.It demands to couple several diode laser beams into one beam to output directly or by an optical fiber to improve the brightness,and it becomes the central issue to adopt the appropriate beam coupling technology which would offer high quality and high efficiency.In order to output high power,we utilized wavelength coupling technology to couple two laser beam of different wavelength together with beam splitter cube (BSC),the key technology and the principle of wavelength coupling is indicated and analyzed in this paper.Using 808nm and 980nm laser diode realize wavelength coupling with high output power,the efficiency more than80% and spot size can be achieved after focusing to the beam size of3×3mm2.
