Femtosecond FBGs can make into all optical transparent fiber materials with a broad variety of fiber coatings without strip the coating from fiber and without recoated in future. It is possible to write FBGs pair into active fibers (Yb, Er, Tm, Bi, Ho doped fibers). Thus additional splicing losses are minimizing and laser efficiency increase. 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.
