← ScienceWhich consequence results when injected pulsed-dye lasers lose coherence?
A)Pulse broadening exceeds transform limit✓
B)Increased self-phase modulation develops
C)Carrier envelope phase remains stable
D)Supercontinuum generation avoids instabilities
💡 Explanation
Pulse broadening occurs as transverse modes shift randomly, increasing the pulse duration because temporal coherence degrades, creating non-ideal bandwidth. Therefore, broadening occurs, rather than spectral stability, because coherence depends on temporal modal stability.
