Difference Between Laser and LED (Simple Table)

 Difference Between Laser and LED

Laser and LED are both sources of light, but they are different in many ways. The main differences are explained below in a simple table.

Difference Between Laser and LED

Laser


1) Laser emits light by stimulated emission

2) Laser light is highly directional

3) Laser light is monochromatic (single colour)

4) Laser light is coherent

5) Laser has high intensity

6) Laser beam has very low divergence

7) Used in optical fibre communication and surgery


LED

1) LED emits light by spontaneous emission

2) LED light spreads in all directions

3) LED light has many wavelengths

4) LED light is incoherent

5) LED has low intensity

6) LED beam has high divergence

7) Used in indicators and lighting

Conclusion

Laser is used where a strong and focused beam of light is required, while LED is used for general lighting and indication purposes.

Introduction to Optical Fibre (Simple Explanation)

  Introduction to Optical Fibre Optical fibre is a modern communication medium used to transmit information in the form of light signals over long distances. What is Optical Fibre? An optical fibre is a thin, flexible strand made of glass or plastic that carries light signals from one place to another. Basic Structure of Optical Fibre An optical fibre consists of three main parts: 1. Core The core is the central part of the fibre through which light travels. 2. Cladding Cladding surrounds the core and has a lower refractive index, which helps in total internal reflection. 3. Protective Jacket The protective jacket protects the fibre from physical damage and moisture. Working Principle of Optical Fibre Optical fibre works on the principle of Total Internal Reflection (TIR). Light entering the core is continuously reflected inside the core and travels long distances with very little loss. Applications of Optical Fibre Used in telecommunication and internet Used in cable TV networks U...

Properties of Laser (One Line Explanation)

 Properties of Laser Laser light has some special properties that make it different from ordinary light. 1. High Intensity Laser light is very intense, which means it has very high energy compared to normal light. 2. Monochromatic Laser light has only one wavelength or one colour, unlike ordinary light which has many colours. 3. Highly Directional Laser light travels in a single straight direction and does not spread much over long distances. 4. Coherent In laser light, all the light waves move in the same phase, which makes the beam strong and focused. 5. Low Divergence Laser beam spreads very little while travelling, so it can cover long distances without losing strength. Conclusion Because of these special properties, lasers are widely used in engineering, medicine, communication, and industry.
