Abstract

We describe the stabilization technique of an optical enhancement cavity using a counter propagating mode. The burst amplification of the injection laser in the main path induces a drastic change in the laser intensity and disturbs the stabilization of the enhancement cavity. We have used a counter propagating mode to achieve a 4% intensity jitter and 0.6 mJ pulse storage inside the cavity at the maximum of the burst region. Our results indicate that the counter propagating mode has the same resonant condition as the main mode and thus becomes useful for stabilizing the enhancement cavity. We also determined that the burst amplification brought about no decrease in the enhancement factor in the cavity due to the degradation of laser quality.
