Fabry-Perot interferometer and mode matching

Abstract

The theory, design, and use of the mirror Fabry-Perot interferometer (FPI) is described in detail .it is important to correctly recognize laser beams of various rays or styles in order to safe certain types of lively link. The Fabry- Perot interferometer is excited via an external laser ray. Part of the study relies on the provision of to combine and change a part of the reflection to form the rules of the resonator. Use a piezoelectric sheet to check one of the reflective resonators back and forth, in order to make the length of each resonator change regularly. As the length continues to change. An important part of the mode is the strategy of organizing the laser column into the resonator. The real mode organization and extensive are except for the Gaussian key mode. When recommending the Fabry-Perot interferometer mode, the specific limits of the resonator will be measured to detect events, decay time, line width, etc.  Mode adjustments are required not only for establishing an appropriate added back the intensity distribution, but for matching the optical phase distribution, in order to achieve the desired results.  This design to explore the properties of an optical resonator; Properties that are common to almost all optical resonators. In addition, it provides the experience of aligning an optical resonator and introducing laser light into an optical resonator, a process known as mode adjustment.
