Abstract

Cascaded Raman wavelength shifting up to the fourth order ranging from 2092 to 2450 nm is demonstrated using a nanosecond pump at 1995 nm in a low-loss As 38 Se 62 suspended-core microstructured fiber. These four Stokes shifts are obtained with a low peak power of 11 W , and only 3 W are required to obtain three shifts. The Raman gain coefficient for the fiber is estimated to ( 1.6 ± 0.5 ) × 10 11 m / W at 1995 nm . The positions and the amplitudes of the Raman peaks are well reproduced by the numerical simulations of the nonlinear propagation.
