摘要： A method of controlling an ultra-short pulse system is described comprising controlling an optical power within the ultra-short pulse system and control-system controlling a width of an optical pulse. In some embodiments, the method also comprises tuning a compressor by controlling a number of passes of the optical pulse through a Bragg grating to control the width of the optical pulse output from the compressor. In other embodiments, the method may comprise tuning a multi-pass stretcher by controlling a number of passes of the optical pulse through a loop of the multi-pass stretcher to control the width of the optical pulse output from the multi-pass stretcher. A method of controlling an ultra-short pulse system may also comprise accessing a control system from a remotely located command station, communicating status information from the control system to the command station, and communicating information from the command station to the control system.

摘要： Methods, devices and systems for generating ultrashort optical linear chirped pulses with very high power by amplifying the pulses so that their temporal duration is longer than the storage time of the amplifying medium. The additional gain factor is related to the ratio of the storage time to the stretched pulse. A preferred embodiment connects a mode locked laser source that generates optical pulses whose duration is stretched with a chirped fiber Bragg grating. Embodiments include methods, devices and systems causing an extreme chirped pulse amplifier (XCPA) effect in an oscillator.

摘要： A chirped pulse amplification (CPA) system and method is described wherein the pulse is stretched using multiple passes through a Bragg grating or compressed using multiple passes through a Bragg grating. A switch may be used to control the number of passes through the Bragg grating, thus, tuning the compressed or the stretched pulse width. The pulse may be directed through an amplifier between the multiple passes through the Bragg grating to apply amplification to the stretched pulse multiple times. The Bragg grating may include a fiber Bragg grating, a volume Bragg grating, or a Bragg waveguide.
