Which consequence results when an optical cavity mirror misalignment impacts laser output?

💡 Explanation

Beam divergence and astigmatism increases because mirror misalignment disturbs the cavity's resonant modes through wavefront distortion, causing off-axis propagation; therefore, divergence occurs, rather than narrower wavelengths, assuming sufficient gain to lase.
