Which outcome occurs when a laser diode's drive current exceeds its rated maximum?

💡 Explanation

Catastrophic optical mirror damage occurs because exceeding the maximum rated current generates excessive heat at the laser facet; this thermal stress rapidly degrades the facet coating due to reduced band gap, therefore COMD is triggered rather than improved performance from greater drive current.
