Fabry-Perot Interferometer (SA-91)
The Fabry-Perot interferometer, or etalon assembly, generates the interference pattern that is characteristic of the spectral features of the laser under test. A simple device that relies on the interference of multiple beams, it consists of two partially transmitting mirrors precisely aligned to form a reflective cavity. Incident light enters the Fabry-Perot cavity and undergoes multiple reflections between the mirrors so that the light interferes with itself many times.

Detector/Amplifier (DA-100)
As the name implies, the detector/amplifier system detects the laser light transmitted through the laser spectrum analyzer, then amplifies the signal for display on an oscilloscope. When considering a laser spectrum analyzer, important points to note are the sensitivity of the detector and the range of acceptable wavelengths.

The detector/amplifier system used with EXFO laser spectrum analyzers is available with a choice of interchangeable photodetectors for use with visible to infrared wavelengths. Its superior, low-noise performance detects signals as low as 1 nW to minimize the laser intensity required for laser spectral analysis.

For convenience, the detector assembly mounts magnetically to the rear of the Fabry-Perot interferometer. This allows continuous monitoring of the spectral output while making adjustments to optimize the performance of the laser spectrum analyzer.
