The unstable ring resonator is a promising architecture for high power solid-state oscillators with intra-cavity adaptive optics. In this paper, we present adaptive compensation of intra-cavity tilt in an Nd: YAG unstable ring laser using a probe bea

A breakthrough result of a kW-level Nd: YAG slab laser with a unidirectional unstable ring resonator is presented. The reverse wave is efficiently suppressed by a diaphragm placed at the focal point of the negative-branch unstable ring resonator. Wit

The edge effects of high-power slab lasers cause severe wavefront distortions with large amplitude and gradients, which is a great challenge for the adaptive optics systems for improving the beam qualities. The standard least-squares wavefront recons

Beam stabilization is critical in an adaptive optics beam clean-up system to improve the power concentration in the desired area during a period of time. In these systems, the average wavefront slope from a Shack-Hartmann wavefront sensor is widely e

Shack-Hartmann wavefront sensors calculate the position of focal spot in each sub-aperture from intensity distributions, the noises of the detector itself would have a certain impact on the detecting accuracy and would lead to inaccurate wavefront de

We present the results that the performances of the atmospheric coherent optical communications improved by a real 127-element adaptive optics system operating in 1550 nm wavelength on a 1.8 m telescope. The mixing efficiency and the BER of the homod

We present adaptive compensation of intracavity tilts based on detecting the direction of the output beams. We use the initial direction of the output beam when the laser cavity is well collimated for reference. Then the difference between the actual
