N2 - Experimental and theoretical studies of the effects of tapering and optical guiding on sideband instabilities are reported. The experiments are performed in the Columbia Raman FEL ({reversed tilde equals} 2 mm). Experiment shows sizeable reductions in sideband amplitudes in an efficiency-enhanced undulator. In the presence of optical guiding in a constant-period undulator, the sideband shift is larger compared with the case when optical guiding does not occur.
