Which risk increases as pulsed laser peak power increases?

A)Optical breakdown within the lens
B)Lower pump current threshold required
C)Reduced heat diffusion from medium
D)Increased mode-locking pulse duration

💡 Explanation

Optical breakdown risk increases due to the intense electric field. The electric field strength exceeds the dielectric strength, and avalanche ionization occurs, initiating laser-induced damage; therefore, the lens cracks, rather than improving the other optical characteristics.
