Multimode fiber laser gratings |
| abstract |
The optically active waveguide laser 30 of the present invention includes a multimode portion 126 for carrying one or more spatial modes at a predetermined wavelength selected from a bandwidth comprising a pump wavelength 64 and a laser irradiation wavelength 66. Include. The multi-mode unit 126 has a first refractive index. The cladding portion 386 is adjacent to the multi-mode portion 126. A multimode grating 60, 56 or 62 is written on at least one section 26 of the multimode portion for reflecting the predetermined wavelength. |
