← ScienceWhich consequence results when Brewster's angle is not maintained when transmitting a polarized laser beam across several glass optical elements?
A)Increased beam power attenuation✓
B)Higher spectral frequency emission
C)Reduced temporal beam coherence
D)Decreased spatial light intensity
💡 Explanation
Increased beam power attenuation develops because Fresnel reflection increases when incidence deviates, resulting in more light being reflected at the glass surfaces, rather than transmitted forward. Therefore the power attenuation increases, rather than enhanced coherence, resulting from a phase match only at Brewster's angle.
