The Inspire Offers

  • User-friendly gap-free tuning from 345 nm to 2.5 µm.
  • Five output ports available: signal output (490-750 nm), idler output (930-2500 nm), fundamental output (690-1040 nm), and doubled fundamental output (345-520 nm)
  • Simultaneous output from either two or three output ports—ideal for applications requiring more than one wavelength such as CARS and SRS imaging
  • HF version with fully-automated hands-free wavelength tuning complete with automated cavity alignment to maintain optimal power and pulse durations
  • Auto version with semi-automated tuning and nearly transform-limited pulse duration flexibility (80-250 fs) for tailoring pulse widths to match experimental conditions

Compatible Power Sensors

To verify and analyze the output power of your Inspire UV 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 Inspire UV, depending on application. Ophir also works with laser system developers to achieve embedded beam diagnostics to monitor system performance as an OEM solution.
