Specifications hold over different repetition rate ranges, depending on the laser model, as follows: Q301 from 10 to 30 kHz, for Q302 from 30 to 70 kHz, for Q303 from 70 to 130 kHz, and Q304 from 40 to 90 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. |
