What is an optical cavity?
, also known as an optical resonator, the optical cavity is arranged to control feedback generated from wave waves. Usually this type of arrangement will include the use of mirrors or other means to reflect these waves to create the desired effect. The optical cavity is an essential part of various types of laser -based devices, allowing control of the direction and intensity of light waves so that the laser can be used for specific purposes. Technology of this type has made it possible to develop laser equipment for a wide range of uses, including safety systems and even saving life procedures for use in healthcare facilities.
The simple configuration of the optical cavity will include at least two mirrors that are carefully placed so that the light waves reflect several times between the mirror surfaces. The final result is the ability to control resonance created by light waves and even control the direction of and the intensity of these waves. Depending on the type of appropriate equippedAlmost any number of mirrors of functioning prisms can be involved.
One of the advantages of the optical cavity is to control resonance generated by light waves, allowing the operator to adjust the frequency using the basic controls of the device. This process can be used to create lasers suitable for everything from soldering on PC boards to assistance in surgery and other tasks related to health care. The optical cavity configuration also serves as safety measures, as the location and number of reflective devices or mirrors effectively set a limit for the intensity of resonance made from the process.
Factors that affect the function of the optical cavity include the size and shape of the mirror used to produce the effect. It is unusual for flat mirrors to be used because of the difficulty of adjusting the mirror position to create the desired effect. They are more often for useCurved mirrors are preferred in the cavity and can be adjusted relatively, so that the correct amount of reflection is achieved. In addition, the length of the participating mirrors will also change the resonance and frequency that is created. Even something as simple as the distance that exists between the mirrors will affect how effectively the optical cavity works.
