Abstract
A multichannel fiber laser whose wavelength range is expansible to increase the number of lasing channel, and whose channel output powers are equalized, in order to provide a useful multichannel laser source having a wide bandwidth is described. The laser comprises a gain offering means; a gain equalizing means; and a resonating means. In addition, a method for designing the spectral profile of a gain equalizing filter for the purpose of this invention is described.
