ABSTRACT:
A photonic bandgap assembly used in a laser device for generating a near-diffraction-limited optical beam that comprises simultaneous multiple wavelengths. The photonic bandgap fiber assembly has a plurality of serially connected segments each having a photonic crystal fiber each being designed to efficiently perform Raman conversion on a pump wavelength to a near-diffraction-limited output wavelength. A first segment of the assembly is connected to a pump laser, and the output wavelength generated by each segment is output to the following segment to serve as a pump beam of the photonic crystal fiber thereof. Therefore, the pump beam is converted in a plurality of output beams with different wavelengths. The output beams can then be selectively recombined and coupled out as a multiple-wavelength optical beam.
