Abstract
This paper describes a tunable fiber soliton laser. This laser is configured as a ring with a silica optical fiber gain medium.A length of 300m conventional fiber provides the negative group velocity dispersion, self-phase modulation and Raman gain effect. The time-dispersion tuning technology is used for wavelength selection, because the Raman gain of silica fiber has a wide spectrum. The different wavelengths have different optical lengths, when they propagate in a optical fiber. We use an active modelocking Nd:YLF Laser which has wavelength 1.313 mn with pulse width of 70ps for pumping source and silica optical fiber of 300m for gain medium and group velocity dispersion compensator.The pulse width(FWHM)of 195fs has been got, the laser wavelength is 1.395 \i m and tunable region of 47nm near 1.397 |i m.
