3. 9.27µm is the predominant wavelength but can typically vary in the range 9.2–9.4µm.
4. Mean average power at 100% AOM duty cycle. The mean average power is proportional to the AOM duty cycle.
5. Guaranteed long term stability is ± 3%.
6. Mean average power at 100% AOM duty cycle. The mean average power is proportional to the AOM duty cycle.
7. At a demand duty cycle of 50%.
