← ScienceWhich outcome occurs when increased laser diode temperature impacts holographic data storage?
A)Reduced writing accuracy✓
B)Increased quantum efficiency
C)Decreased mode hopping occurrence
D)Improved beam pointing stability
💡 Explanation
Reduced writing accuracy occurs because increased temperature affects the diode's coherence length, leading to decreased interference fringe contrast using optical path matching during holographic recording. The interference diminishes, and this reduces writing contrast rather than improving stability; therefore, accuracy declines.
