Bismuth-doped all-fiber mode-locked laser operating at 1340 nm
We demonstrate a 1340 nm mode-locked Bismuth (Bi)-doped fiber laser without any saturable absorber. The effect of pump power on pulse width is studied, and a variation from 1.5 to 3 ns is reported.

Stable operation of the mode-locked laser is verified from the radio-frequency spectrum with a fundamental repetition rate of 6.3 MHz, and SNR of 65 dB.

Abstract

We demonstrate a 1340 nm mode-locked Bismuth (Bi)-doped fiber laser without any saturable absorber. The effect of pump power on pulse width is studied, and a variation from 1.5 to 3 ns is reported. The output of the mode-locked Bi-doped fiber laser is further amplified using a master oscillator power amplifier configuration, and a peak power of 1.15 W is achieved. Soliton bunching is observed, and a true pulse width of 1.2 ps is reported from the measured autocorrelation trace. Stable operation of the mode-locked laser is verified from the radio-frequency spectrum with a fundamental repetition rate of 6.3 MHz, and SNR of 65 dB.
