Abstract :
We constructed an electro-optic sampling (EOS) system using a passive mode-locked fiber laser including nonlinear amplifier loop mirror (NALM). We used an optical band-pass filter and a polarization dependent isolator to get a pure single soliton pulse having the stable polarization state. The pulse width and the repetition rate were about 600 fs and 2 MHz respectively. We could achieve the impulse response measurement of the Schottky-type InGaAs photodetector (PD) using EOS system utilizing this fiber laser.
