For many nonlinear optical process, it is desirable to maximize the product of the intensity and the interaction length. In this paper, very long subwavelength-diameter optical fibers with low optical loss about 0.1 dB cm-1 were fabricated with a new drawing process by heating the standard single mode fiber with a designed electric strip heater. Pumping the taper fibers with 532 nm mode- locked peco-second laser, we observed exclusive SRS phenomena appeared in these fibers with low pump power and fiber length.
