Characterization Of Unstable Resonator Using Variable Reflectivity Mirror
The characterization of unstable resonator using Super-Gaussian mirror is analysed theoretically. Its cavity parameters have been designed for getting optimum laser brightness and its output characterization has been investigated experimentally at Φ20 mm Nd:glass laser. The output them has near diffraction limited divergence of 0. 192 mrad (full angle) and has output energy as high as 92% of that of the conventional unstable resonator.
