摘要
Q-switched and mode-locked pulse generation in Erbium-doped fiber lasers (EDFLs) are demonstrated using Poly [2-methoxy-5-(2-ethylhexyloxy)-1,4-phenylenevinylene] (MEH-PPV) organic semiconductor material as a saturable absorber (SA) for the first time. The MEH-PPV was prepared in the form of a thin film having a modulation depth of 12% and saturation intensity of 40 MW/cm(2). The SA was placed in a laser cavity to produce a stable Q-switched operating at 1564.0 nm. The maximum repetition rate of 78.62 kHz, minimum pulse width of 3.54 mu s and maximum pulse energy of 59.45 nJ were attained at 125.2 mW pump power. On the other hand, by incorporating an additional 100 m long single mode fiber, the mode locked EDFL self-started as the pump power was raised above 125.2 mW. The soliton pulse was obtained due to the enhancement of the nonlinearity in the cavity. The mode-locked laser operated at 1568.5 nm with a fixed repetition rate of 1.859 MHz and pulse width of 2.97 ps.
