We study the factors that ultimately limit the performance of an external enhancement resonator for optical second-harmonic generation (SHG). To describe the resonant SHG process we introduce a theoretical model that accounts for the intensity-dependent cavity loss that is due to harmonic generation and that also includes a realistic assumption about the shape and the frequency width of the laser mode. With the help of this model we optimized the performance of a doubling cavity based on a lithium triborate (LBO) crystal. This cavity was used for frequency doubling the output of a single-frequency titanium-doped sapphire laser at 850 nm. We were able to push the total second-harmonic conversion efficiency to 53% (a 1.54-W pump resulted in 820 mW of second-harmonic light), which to our knowledge is the best result ever reported for a LBO-based doubling cavity.

  13. To get a continuous scan range larger than ±3 GHz, one could mount a Brewster plate into the cavity. It could then take care of slow variations while the PZT-driven mirror would correct for higher frequencies.
  14. The Hänsch–Couillaud stabilization method is not suitable for spectroscopic applications, especially when a broad wavelength range is required. In carrying out the wavelength tuning measurements we applied the Pound–Drewer–Hall stabilization scheme [see R. W. P. Drewer, J. L. Hall, F. V. Kowalski, J. Hough, G. M. Ford, A. J. Munley, and H. Ward, “Laser phase and frequency stabilization using an optical resonator,” Appl. Phys. B 31, 97–105 (1983)]. The power stability with both of these two techniques remained the same (at least within the limit that we could detect). [CrossRef]
  15. Absolute power values are uncertain to ±2.5% of the stated value because of uncertainty in detector calibration.
