Abstract
We experimentally demonstrate an Er3+-doped femtosecond mode-locked optical fiber laser which operates at the 1550-nm wavelength and generates ultrashort optical pulses with width of 270 fs, repetition frequency of 20 MHz, and average output power of 146μW. We find that the pulse width keeps stable increasing when the pump source optical power is enhanced in the range from 25 mW to 60 mW. However, if the pump source optical power exceeds 60 mW, the oscillation phenomenon would occur in pulses width. To be used as an optical source in fiber-optic communications system, the output femtosecond pulses from the mode-locked laser are also amplified specially through an Er3+-doped optical fiber amplifier. The relationships between pump optical power and amplified characteristics including amplified optical pulses width, amplified average optical power, amplified single optical pulse energy, amplified gain and spectrum shape are studied experimentally in the amplified experiment.
