← ScienceWhich consequence results when optical pumping fails in krypton laser?
A)Decreased population inversion, reduced gain✓
B)Increased krypton ionization, plasma instabilities
C)Mirror misalignment, resonant cavity losses
D)Wavelength shift, amplified spontaneous emission
💡 Explanation
Reduced gain follows optical pumping failure because the population inversion mechanism is not sustained; therefore the amplification diminishes rather than enhanced ionization or mirror misalignment, which depend on alternate conditions.
