Which risk rises when a pulsed laser's burst duration increases?

💡 Explanation

Increased pulse duration enhances the cumulative **thermal blooming** effect because uneven heating raises the refractive index of optical elements, therefore the beam distorts severely because the temperature distribution changes the refractive index, rather than shorter pulses allowing insufficient time for this effect.
