Thulium doped fiber laser with a limited pulse width of 560fs
Abstract
In this paper, by shortening the cavity length, we have realized all-fiber Tm-doped fiber laser with pulse width less than 600 fs based on nonlinear polarization rotation effect. Under the condition of pump power of 0.281 W, the traditional soliton limit pulse is realized by adjusting the polarization controllers. The pulse width is 560fs and consistent with the theoretical calculation of the limit pulse width 569fs, repetition frequency is 55.25 MHz, the central wavelength is 1978.34 nm and the 3dB spectral width is 7.25 nm. The traditional soliton index is helpful to improve the application of ultrafast Tm-doped fiber laser in mid-infrared light source and medical operation.
