EagleEye

The EagleEye Optical Spectrum Analyzer (OSA) is a compact unit for measuring spectral characteristics of cw lasers. The Eagle-Eye, like any other conventional OSA device, can analyze a laser spectrum by scanning it’s cavity.
This approach has a resolution limited by the EagleEye’s cavity finesse, which is in the order of some MHz.
The EagleEye devices surpass this limit by using a lock, loose and look procedure. Using this approach, a much higher resolution for laser linewidths is achieved. Laser linewidths as low as 20 kHz are resolved.
