Product info here (rack-mounted version here) Brain dump: - We have two of these, with the rack-mounted version serving as back-up; located in rack 64B; the back-up has been tested for functionality previously, so it should be plug and play
- These can be wavelength tuned, but it's a little finnicky and laggy (especially on the rack-mounted version, which is tuned using a pot on the front of the unit), so it's best not to touch them; in the ancient past, these units got shuffled around with the factory supposedly in order to get the tuning range set appropriately for the system it would be seeding
- There is a way to read out information from these units from the back panel, but there is no way to actually control these units from the back panel – no hope for writing an IOC
- Only plugs in the back should be power and interlock
- System should show temp stable and second mode suppressed or else there will be major performance/stability issues; depending on how long it's been off or how unstable the environment is, this may be fine right away or it may take ~30-60min
- Front display should show ~135-140mW and 1053.045nm when running
- Past experimenting didn't show any effect of using ACC vs. APC mode nor RIN suppression on vs. off
- Upgrade ideas:
- This is essentially the only laser of its kind I know of that doesn't use a fiber pre-amplifier somewhere before the free-space amplifier. Sometimes this is located before or after the EOM (or both), but it can provide way better performance this way.
