How Fabry-Perot laser source is working explain the operation?

A Fabry–Pérot laser diode (FP laser diode) is the most common type of laser diode, having a laser resonator which is a Fabry–Pérot interferometer. This means that substantial light reflections occur at both ends, but not within the gain medium.

A Fabry-Perot (FP) laser diode is a type of laser diode that has two broad-band optical mirrors at either end of the diode which forms an optical cavity. The FP laser diode uses AlGaAs, InGaAsP, AlGaInP, etc as the gain medium. Fabry-Perot laser diodes are available as free-space and fiber-coupled types. FP laser diodes are usually available in the ...

What is the working of Fabry-Perot interferometer?

The Fabry-Perot interferometer uses the phenomenon of multiple beam interference that arises when light shines through a cavity bounded by two reflective parallel surfaces. Each time the light encounters one of the surfaces, a portion of it is transmitted out, and the remaining part is reflected back.

What does a laser diode do?

A laser diode is an optoelectronic device, which converts electrical energy into light energy to produce high-intensity coherent light. In a laser diode, the p-n junction of the semiconductor diode acts as the laser medium or active medium.

What does a Fabry Perot Etalon do?

A Fabry–Pérot etalon can be used to make a spectrometer capable of observing the Zeeman effect, where the spectral lines are far too close together to distinguish with a normal spectrometer. In astronomy an etalon is used to select a single atomic transition for imaging. The most common is the H-alpha line of the sun.

What is the typical linewidth of a Fabry Perot FP laser?

Figure 6.8 Fabry - Perot semiconductor laser. A typical F-P laser diode linewidth ranges from 10 – 100 MHz. Much narrower emission spectrum can be achieved for long external cavity F-P lasers.

Why we get circular fringes in Fabry Perot interferometer?

The phase relationship between the transmitted rays depends on the angle at which each ray enters the cavity and on the distance between the two mirrors. The result is a circular fringe pattern, similar to the Michelson pattern, but with fringes that are thinner, brighter, and more widely spaced.

What is the difference between Fabry Perot interferometer and Fabry Perot Etalon?

An etalon is an optical interferometer that consists of two glass plates, separated by a small,flxed distance. A beam oflight undergoes multiple reflections between the surfaces of the glass plates. ... The Fabry Perot interferometer consists of two flat, parallel, semitransparent mirrors separated by a certain distance.

What is the type of fringes formed in Fabry-Perot interferometer?

The fringes in a Fabry-Pérot interferometer are formed with light incident nearly normally (θ ≈ 0) on the air film bounded between the parallel inner faces of a pair of glass plates (for precision work, the space between the glass plates is evacuated) because the separation between the successive fringes is maximum for ...

How long does a laser diode last?

Typical lifetime of laser diode modules are 25,000 to 50,000 hours. If the laser diode temperature continues to rise exceeding the maximum operating temperature, the diode can be catastrophically damaged or the long term performance may degrade significantly.

How does a Fabry Perot interferometer work?

  • Fabry–Perot interferometer. In a fiber sensor, a Fabry–Perot etalon can be formed using one end of the fiber itself (with a reflective coating deposited on it) and a separate, movable mirror. Alternatively, two mirrored surfaces can be used, and the fiber simply transmits the light.

What is Fabry-Perot cavity?

  • A Fabry-Perot cavity is formed by the cleaved endfaces, which have a power reflectance of approximately 30% due to the high index of refraction of the gallium arsenide, n = 3.5. Gain occurs in an active region in a thin plane at the junction. Laser oscillation will produce an output beam at the cleaved faces because of the higher overall gain ...
