Wavelength Tunable Dissipative Soliton Mode-locked Fiber Laser Based on Nonlinear Amplifier Loop Mirror
A figure-8 cavity wavelength-tunable mode-locked Ytterbium-doped fiber laser based on nonlinear amplification loop mirror is reported. When pump power is 240 mW, the dissipative soliton is output with a central wavelength of 1 064.1 nm, 3 dB bandwidth of 7.7 nm, repetition rate of 18.8 MHz, optical signal noise ratio of 71.2 dB and pulse duration of 867 fs, respectively. In addition, wavelength tunable of the mode-locked fiber laser at 1 032.8~1 065.1 nm and 1 037.4~1 041.9 nm can be achieved by adjusting the polarization controller and pump power respectively. The characteristics of the spectra and pulses in different mode-locked states are explored, and a Gaussian pulse whose time bandwidth product is close to the Fourier transform limit is obtained. The fiber laser is simple in structure and easy to tune, and has a stable performance, which provides technical reference for achieving wavelength tunable and dissipative soliton mode-locked.
