Footnotes:

  1. Due to our continuous product improvement program, specifications may change without notice. Specifications only apply when the 3900S is pumped by a Spectra-Physics Millennia eV 10 W or 5 W pump laser.
  2. Power specified using the appropriate pump laser
  3. RMS, measured in a 10 Hz to 1 MHz bandwidth
  4. For a 2-hour period after a 1 hour warm up and <±3°C temperature change
  5. Specifications apply to operations at the peak wavelength
  6. Using additional blue optics
  7. Using additional x-long optics

Features

Compatible Power Sensors

To verify and analyze the output power of your 3900s laser, we recommend the Ophir 3A (7Z02621) thermal power sensor and Centauri laser power meter.  Additional information on this laser measurement equipment can be found on the ophiropt.com website.  Other Ophir sensors and meters may also be suitable for the 3900s, depending on application. Ophir also works with laser system developers to achieve embedded beam diagnostics to monitor system performance as an OEM solution.
