Abstract

In this work, the full emission spectrum of Tm-doped fiber (1700 nm – 2000 nm) is employed for tunable noise-like pulse operation. By using an Acousto-Optic Tunable Filter (AOTF), the operation wavelength can be electrically tuned within the 300 nm wavelength range. Based on an all-anomalous dispersion cavity and hybrid mode-locking technique, noise-like pulse operations at different wavelengths are obtained with a 10-dB spectral width ranging from 22 nm to 37 nm and output average power from 25.9 mW to 104 mW. The cavity repetition is 35 MHz. Additionally, when the laser operates in the water absorption region, we observe giant pulses with intensity several times higher than average pulse intensity are generated in the output pulse train.
