Dense wavelength multiplexing and 35 µm-fiber coupling of wavelength chirped high power diode laser bars
Abstract
We present a flexible, modular and cross-talk free concept for dense wavelength beam combining of HPDL by use of ultra-steep dielectric filters. Five emitters of one mini bar are coupled into a 35 µm fiber. Experimental results of internally and externally stabilized HPDL are presented.
