SUMMARY
The discussion centers on the relationship between fluorescence lifetime and pulse duration in pulsed nitrogen lasers. It is established that the upper-state lifetime exceeds the pulse duration, enabling energy storage in the gain medium before lasing occurs. A population inversion is essential for effective lasing, where stimulated emission is favored over absorption. The rapid depletion of the upper state during lasing contrasts with the slower, random occurrences of fluorescence prior to this process.
