- In the case of a fixed wavelength (FW), a single wavelength can be selected from the Signal or Idler range. Signal may have an accessible Idler pair, and vice versa.
- I‑OPA‑F broad-bandwidth pulses are compressed externally. Typical pulse duration before compression: 120 – 250 fs, after compression: 25 – 70 fs @ 650 – 920 nm, 40 – 100 fs @ 1200 – 2000 nm.
- Output pulse duration depends on the selected wavelength and the pump laser pulse duration.
- Expressed as normalized root mean squared deviation (NRMSD).
- Conversion efficiency is 1.2% at the peak of the SH package; specified as the percentage of pump power.
- Specifications are guaranteed for a maximum temperature variation of ± 1ºC and humidity variation of ± 10%.
- I-OPA is powered by the same electrical source as the pump laser. Thus, refer to the pump laser electrical requirements.
