Which outcome occurs when a gallium arsenide laser is stressed?

A)Increased electron-hole recombination probability occurs
B)Stable Fermi energy level gets maintained
C)Lasing wavelength exhibits a blue shift
D)Reduced photon emission cross-section develops

💡 Explanation

Increased stress enhances defects, causing higher electron-hole recombination via Shockley-Read-Hall (SRH) recombination mechanism because these defects act as traps inside the band gap. Therefore, non-radiative recombination increases, diminishing laser efficiency rather than maintaining Fermi levels.
