A method and apparatus for generating optical pulses using an active mode-locking laser that includes a first modulation device, optical selectio n device, a second modulation device and an amplification device. The method includes the steps of using the first modulation device to modulate a lightwave, selecting a modulation lightwave signal having a high frequency component by passing a lightwave through the optical selection device in a first direction, using the second modulation device to modulate a lightwave, selecting a modulation lightwave signal having a high frequency component by passing a lightwave through the optical selection device in a second direction, amplifying the lightwave selected by the above step, and supplying the amplified lightwave to the first modulation device.
