In this paper, we report first lasing results in the near-UV and visib
le spectral ranges with the OK-4/Duke storage ring - the first storage
ring FEL operating in the United Slates. The OK-4/Duke FEL was commis
sioned in November 1996 and demonstrated lasing in the 345-413 nm rang
e with extracted power of 0.15 W. In addition to lasing, the OK-4/Duke
FEL generated a nearly monochromatic (1% FWHM) gamma-ray beams. In th
is paper, we describe initial performance of the OK-4/Duke storage rin
g FEL and gamma-ray source in this demonstration experiment. We briefl
y discuss the present status of the project and its future user progra
