AS-Photonics has offered consulting services for over 12 years. We have completed projects for more than 50 clients in academia, government laboratories, and defense industries. Our rates are reasonable and our response is fast. Topics we have experience in are:

Crystal nonlinear optics

  • Quantitative modeling of laser frequency conversion via optical parametric oscillators, optical parametric amplifiers, optical parametric generators, and sum-frequency generation.
  • Continuous-wave to femtosecond devices
  • Beam propagation method (BPM) modeling

Fiber lasers and amplifiers

  • Yb- and Tm-doped lasers and amplifiers
  • Transverse mode instability (TMI) models
  • Stimulated Brillouin scattering (SBS) models
  • Stimulated Raman scattering (SRS) models
  • Four-wave mixing (FWM) models
  • Transverse mode calculations

Thermal effects

  • Self-consistent nonlinear optics and thermal models of crystals
  • Self-consistent gain and thermal BPM models of fibers
