Which risk increases when a pulsed laser experiences thermal blooming?

A)Reduced spot accuracy on target
B)Increased stimulated emission rate
C)Total internal reflection efficiency
D)Stronger second harmonic generation

💡 Explanation

Thermal blooming occurs due to localized heating, driving changes in refractive index; this causes beam divergence when focusing, resulting in reduced precision because this is a thermal effect distorting the beam, therefore spot accuracy decreases on defined targets rather than other laser properties being enhanced.
