FBG Raman laser
ARTICLE GTL-FBG-RL-880
Highly efficiently multicascaded Raman lasers based on phosphosilicate fibers can be created at different wavelength. Raman shift by 1330 cm-1 in opposite to Ge-doped fibers is approximately three times larger. Output emission spectrum of two-cascade 1.48 µm Raman fiber laser is presented in the graph.
