← ScienceWhich consequence results when the Faraday effect rotates laser polarization?
A)Intensity modulation from fixed polarizer✓
B)Mode-locking of the laser cavity
C)Increased laser beam divergence
D)Increased laser pump efficiency
💡 Explanation
Intensity modulation occurs because the changing polarization, via the Faraday effect, interacts with a static polarizer to block varying amounts of power. The mechanism is polarization modulation driven by magneto-optics; therefore intensity varies, rather than mode-locking, divergence, or pumping, all driven differently.
