We developed a nonlinear crystal cavity to trap high-power laser pulses, enhancing Compton light sources. This method achieved up to 40x average power enhancement for frequency-doubled picosecond pulses.

Area of Science:

  • Nonlinear optics
  • Laser physics
  • Particle accelerators

Background:

  • Compton-scattering-based light sources require high-power laser pulses for efficient operation.
  • Enhancing the average power and flux of these laser pulses is crucial for advancing light source capabilities.

Purpose of the Study:

  • To demonstrate a novel recirculation cavity design for trapping the second harmonic of high-power laser pulses.
  • To investigate the potential of this scheme for increasing the efficiency and flux of Compton-scattering light sources.

Main Methods:

  • Utilized a nonlinear crystal-based short pulse recirculation cavity.
  • Trapped the second harmonic of incident high-power laser pulses.
  • Measured average power enhancement for frequency-doubled picosecond pulses and high-energy ps pulses.
