Main parameters of optical fiber laser.(with pulse laser for example)
Peak Power: maximum output power at high level during pulse period
Average Power: Average power in pulse period.
Pulse broading: Duration of output power at high level in pulse period.
Pulse period: the total time required for one pulse square wave.
Frequency: Number of pulses per unit time, called the reciprocal of the cycle.
Duty ratio: The ratio of pulse broading to the pulse period
Pulse energy: The sum of output energy in a pulse period.
Energy density: Total energy accepted in 1 cm2 per unit time.
