Figure 2. Erbium doped fiber laser mode-locked with carbon nanotubes.

Figure 2

A ring cavity fibre laser comprises high concentration erbium doped fibre (EDF), polarisation controllers (POCs), wavelength division multiplexing (WDM) coupler, optical isolator (OISO) to provide unidirectional lasing, saturable absorber in the polymer film with carbon nanotubes (SA: CNT), and output coupler (OUTPUT C). The cavity is pumped via 980/1550 WDM by 976 nm laser diode (LD). Output lasing has been analysed with an optical spectrum analyser (OSA), and in-line polarimeter (IPLM). The resolution of IPM was 2 ns and the number of samples was 10 M.
