    摘要： A laser oscillator to generate a pulsed light beam includes an output coupler mirror, configured to reflect a reflected portion of the pulsed light beam back into the laser oscillator, and to couple an outputted portion of the pulsed light beam out from the laser oscillator; an end-mirror, configured to return the pulsed light beam into the laser oscillator; a gain material, positioned between the output coupler mirror and the end-mirror along an optical path, configured to amplify the pulsed light beam; a self-starting saturable absorber, configured to self-start a pulsed mode-locking operation of the laser oscillator; and a pulse-shaping saturable absorber, configured to shape pulses of the pulsed light beam into laser pulses with a pulse length of less than 1,000 femtoseconds.

    摘要： Designs and techniques for constructing and operating femtosecond pulse lasers are provided. One example of a laser engine includes an oscillator that generates and outputs a beam of femtosecond seed pulses, a stretcher-compressor that stretches a duration of the seed pulses, and an amplifier that receives the stretched seed pulses, amplifies an amplitude of selected stretched seed pulses to create amplified stretched pulses, and outputs a laser beam of amplified stretched pulses back to the stretcher-compressor that compresses their duration and outputs a laser beam of femtosecond pulses. The amplifier includes a dispersion controller that compensates a dispersion of the amplified stretched pulses, making the repetition rate of the laser adjustable between procedures or according to the speed of scanning. The laser engine can be compact with a total optical path of less than 500 meters, and have a low number of optical elements, e.g. less than 50.
