Overview of FP Laser
As the world becomes more technologically evolved, more and more devices are invented on a daily basis to make human life more comfortable and easy. One such significant advancement we saw was in the light and laser industry. There are many different types of lasers available to fulfil the varying demands of various sectors.
This blog will provide an overview of one such laser, known as the FP Laser. In brief, we’ll learn what it is, how it works, and what applications it has. Let’s get started.
What Is FP Laser?
The FP laser, also known as the Fabry-Perot interferometer, makes use of the multiple beam interference phenomena, which occurs when light passes through a cavity enclosed by two reflective parallel surfaces.
When light strikes one of the surfaces, a portion of it is transmitted out, and the remainder is reflected back. The net result is that a single beam is split into numerous beams that interfere with each other.
Multiple reflections between two closely spaced partially silvered surfaces are used in the Fabry Perot interferometer or the FP laser. Each time the light reaches the second surface, a portion of it is transmitted, resulting in several offset beams that might interfere with one another.
The enormous number of conflicting rays results in an exceptionally high-resolution interferometer, similar to how several slits in a diffraction grating increase its resolution.
