Walled Carbon Nanotubes

We propose a single-wavelength-tunable and dual-wavelength-switchable Tm-doped fiber soliton laser with single-walled carbon nanotubes. The laser can deliver single-wavelength mode-locked pulse tunable from 1892 nm to 1924 nm. Dual-wavelength mode-locking operation can also be achieved by increasing pump power and rotating the polarization controller (PC), meanwhile the wavelength can be switched between 1883/1894 nm and 1905/1910 nm. Both the tunable and switchable operations are realized with great ease by solely adjusting the parameters of PC. The proposed Tm-doped fiber laser can operate in two mode-locking states, which is helpful for further understanding of the mode-locking mechanism and useful for practical applications.

Soliton mode-locked Erbium-doped fiber laser (EDFL) using single walled carbon nanotubes (SWCNTs) was experimentally demonstrated. In this work, SWCNTs was prepared by embedding into polyvinyl alcohol (PVA) as a saturable absorber. The laser generates a soliton pulse, which operates at 1570 nm region without any additional spectral filter as a 980 nm pump power is increased above the threshold value of 60 mW.  The output solitons have a pulse duration of 0.7 ps with a repetition rate of 18.98 MHz. At pump power of 130 mW, the pulse energy and peak power are approximately 0.032 nJ and 43 W.
