Which spectral change occurs in ruby lasers under pressure?

💡 Explanation

The compression of ruby crystals causes closely spaced energy levels as atoms move closer, increasing phonon occupancy because this increases electron-phonon interactions; so spectral linewidth broadens, therefore, rather than cleaner mode-locking or minimization of loss since pressure induces more disruptions.
