Which outcome occurs from thermal expansion inside pulsed laser amplifiers?

A)Beam divergence increases significantly✓

B)Wavelength becomes intrinsically more stable

C)Gain saturation reduces rapidly

D)Output polarization remains highly uniform

💡 Explanation

Thermal expansion causes variations in the refractive index through thermo-optic effect; therefore, beam divergence greatly increases because the changing index acts as a lens, rather than maintaining cohesion as in solid-state cooling.
