Performance Comparison of the Nonlinear Curvature and Shack-Hartmann Wavefront Sensors in Strong Turbulence
Sam J. Potier, Arlene J. Aleman, Justin R. Crepp +1
Strong turbulence induces spatial variations in beam intensity that hinder the reconstruction process of many commonly deployed adaptive optics (AO) systems that use gradient-based…
Developing an Error Budget for the Nonlinear Curvature Wavefront Sensor
Sam Potier, Justin Crepp, Stanimir Letchev
Consistent operation of adaptive optics (AO) systems requires the use of a wavefront sensor (WFS) with high sensitivity and low noise. The nonlinear curvature WFS (nlCWFS) has been…
Spatial frequency response and sensitivity of the nonlinear curvature wavefront sensor
Stanimir Letchev, Jonathan Crass, Justin R. Crepp +1
The nonlinear curvature wavefront sensor (nlCWFS) has been shown to be a promising alternative to existing wavefront sensor designs. Theoretical studies indicate that the inherent…
Measuring Phase Errors in the Presence of Scintillation
Justin R. Crepp, Stanimir O. Letchev, Sam J. Potier +2
Strong turbulence conditions create amplitude aberrations through the effects of near-field diffraction. When integrated over long optical path lengths, amplitude aberrations (seen…
Optical cavity for enhanced parametric four-wave mixing in rubidium
E. Brekke, S. Potier
We demonstrate the implementation of a ring cavity to enhance the efficiency of parametric four-wave mixing in rubidium. Using an input coupler with 95% reflectance, a finesse of 1…
