Which limit is surpassed when pumping exceeds threshold?

💡 Explanation

Achieving threshold pump power within a laser medium overcomes losses and stimulates coherent photon emission because population inversion drives stimulated emission, therefore light amplification begins, rather than spontaneous losses increasing, at threshold.
