Effect of adjustment structure design on laser stability

Abstract

Output stability is crucial for a laser system or a laser oscillator. Moreover, the adjustment mechanism plays an important role in structural stability. In this study, we present an adjustment structure in view of the instability introduced by the adjustment mechanism. Results show that the improved structure greatly enhanced the stability of the optomechanical structure as opposed to the common structure. Driving and stability tests were conducted for both the common and improved adjustment structures with two kinematic optical mounts. The results further show that the improved structure achieves better position stability.
