Packet I: Bonus 6

In one process, the time between these phenomena is bounded by an expression whose numerator contains the time–bandwidth product of a distribution, which for Gaussian profiles is 0.441. For 10 points each:
[10h] Name these phenomena that were generated in a Kerr cell by Hellwarth and McClung in 1961 through a process that periodically adjusts the Q-factor of a resonator.
ANSWER: laser pulses [accept pulsed lasers; prompt on lasers; prompt on laser peaks or laser intensity peaks by asking “what causes those?”]
[10m] Pulse generation can occur through a process that is said to “lock” either these patterns or phase. Coupled systems produce the “normal” form of these patterns at resonant frequencies.
ANSWER: modes [accept normal modes or mode-locking]
[10e] Another method for pulse generation is gain-switching, where the gain of a laser is the change in this quantity. In electronic amplifiers, gain is usually quantified as a ratio of this quantity measured in watts.
ANSWER: power [accept optical power]
