Abstract

In order to obtain the multiband laser source of laser multi-spectrum detection, the method using spectral beam combining in an external cavity to obtain the multi-spectral laser was proposed. The experimental results of spectral beam combining for two fiber lasers using large-mode-area Er³⁺/Yb³⁺ co-doped double-cladding fiber as the gain medium in an external cavity are reported. 3dB linewidth of 29.3nm and 11.52nm respectively between two spectra was obtained. Experimental results show that spectral beam combining in an external cavity is a feasible approach for obtaining the multi-spectral laser sources.
