Abstract:
In this paper a novel, radially varying birefringent output coupler is analyzed both theoretically and experimentally. This output coupler, a dimpled half waveplate, is designed to obtain better beam quality from unstable ring resonators. A theoretical model for its transmission when followed by a polarizer is developed. Since the transmission of the dimpled waveplate is a function of various parameters such as the birefringent material, dimple diameter, radius of curvature, and wavelength, the effect of these parameters on the transmission is studied. Using the theoretical equations, the dimpled waveplate design parameters are determined to achieve the necessary transmission. Two experimental procedures used to characterize the dimpled waveplates are described. One is designed to investigate its average transmission and the other to plot its transmission profile. The experimental results are within 5% error of the theoretical calculations for the peak and average transmissions. Finally, the unstable ring laser with the novel dimpled waveplate output coupler is demonstrated.
