A novel small-period wiggler constructed of edgy-wound bifilar-helical conducting sheets with ferro-magnetic cores, intended for free-electron lasers, is presented. The performance characteristics of the wiggler fields with 10 mm period are measured. A field as high as 1,500 G has been obtained. Free-electron lasers with this new small-period wiggler have been investigated numerically with a three dimensions nonlinear theory. Simulation results estimated that a radiation power of 20.2 MW and frequency of 170 GHz with efficiency 5.1% can be obtained. It is feasible to make Raman free-electron lasers with this type of wiggler operating in the wavelength range of millimeters and submillimeters with a relative low electron energy (< 500 keV) beam.
