1. Specification holds over different repetition rate ranges, depending on the laser model, as follows:
Q331 from 10 to 30 kHz, for Q332 from 30 to 70 kHz, for Q333 from 70 to 130 kHz.
2. Ambient temperature constant ±2°C.
3. Averaged for 1 hour after >80 minutes of continuous operation.
4. Pulse duration measured according to method detailed in JDSU application note titled “Optical Pulse Width Measurement Techniques for Q-Series Lasers.”
5. Pulse Energy Fluctuations = σ / μ x 100%, σ = standard deviation, μ = average pulse energy.
6. Measured after more than 80 minutes of continuous operation.
