← ScienceWhich consequence results when laser light encounters thin-film interference?
A)Chromatic dispersion of output beam✓
B)Increased amplification within laser cavity
C)Optical components thermal lens formation
D)Reduced gain medium excitation threshold
💡 Explanation
Thin-film interference causes variations in the reflected or transmitted wavelengths because constructive and destructive interference alter the spectral composition; therefore chromatic dispersion results, rather than gain changes or thermal effects influencing the cavity.
