What is Coherent Source?
Coherent Source refers to the sources that produce waves with a constant phase relation. In simple terms these sources generate waves in which the crests and troughs of emitted waves align or maintain a consistent phase difference as they move through space-time. This phase consistency allows the waves to interact predictably either in constructive interference or destructively, creating such phenomena as patterns of interference.
Coherent Source of Light
Coherent Source of Light are those light-emitting sources that emits light of the same frequency, same wavelength and same phase or constant phase difference
Coherent Source Example
Laser is an excellent example of Coherent Source. Let’s understand why laser is an coherent source
- In a laser, emitted light waves are in phase.
- This causes sharp and predictable interference patterns.
- It coherence enables the laser to emit a focused highly directional beam of light.
- Lasers are considered essential for applications like cutting, medical procedures and fiber optic data transmission due to coherent properties.
- Unlike common light sources with random wave phases, lasers produce waves that oscillate together to enable predictability and control.
Coherent Source
Coherent Source is the source of waves that produce waves with the same frequency, same wavelength, and constant phase or constant phase difference. Coherent Sources are important in wave optics as they provide conditions for interference of waves to produce highly focussed and directional beam of light.
In this article, we will learn about coherent source, its types, characteristics, how to produce coherent source, its application and difference between coherent and incoherent source in detail.
