Fabrication of submicron-diameter silica fibers using electric strip heater.
In nonlinear optical frequency conversion process, it is desirable to maximize the product of the intensity of pump laser and the interaction length in order to achieve maximum conversion efficiency. In this paper, long and unbroken submicron-diameter optical fibers with low optical loss about 0.1dB/cm were fabricated with a new drawing process by heating the conventional single mode fiber using a designed electric strip heater. Pumped by a 532 nm mode-locked pico-second laser, enhanced SRS phenomena can be observed in the submicron-diameter fibers with relative low pump power.
