Depressed cladding erbium-doped fiber laser passively mode-locked with carbon nanotube saturable absorber
A depressed cladding erbium doped fiber (DC-EDF) laser with a carbon nanotube saturable absorber is proposed and demonstrated. The laser is able to generate a mode-locked output with a narrow pulse width of 0.77 ps at a lasing wavelength of 1496 nm. A 200 m long single-mode fiber together with the D...

| Summary: | A depressed cladding erbium doped fiber (DC-EDF) laser with a carbon nanotube saturable absorber is proposed and demonstrated. The laser is able to generate a mode-locked output with a narrow pulse width of 0.77 ps at a lasing wavelength of 1496 nm. A 200 m long single-mode fiber together with the DC-EDF, with a negative and positive dispersion respectively is used to balance the effect of dispersion and the non-linearity of the system. The output is highly stable, with a signal to noise ratio in the radio frequency domain of 51.2 dB as well as a pulse energy, average output power and repetition rate of 58.9 pJ, -12.75 dBm and 900.9 KHz at the maximum pump power. The proposed laser would have significant applications for S-band communications systems. © 2019 Astro Ltd. |
