Laser and Optic Fibre
Lasers and Fibre Optic is a chapter which is basically in my 1st year of undergrad engineering physics. So I tbh made it for me but this is useful for everyone as it has basics and definitions for so.

Laser and Optic Fibre
Laser
Definition and Function
A laser is a device that emits light through a process of optical amplification based on the stimulated emission of electromagnetic radiation.
Lasers have a specific wavelength and produce a highly focused beam of light.
Types of Lasers
Solid-State Lasers
These lasers use a solid material, such as a crystal or glass, as the active medium.
Examples include ruby lasers, Nd:YAG lasers, and semiconductor lasers.
Gas Lasers
These lasers use a gas as the active medium.
Examples include helium-neon lasers, carbon dioxide lasers, and argon lasers.
Semiconductor Lasers
Also known as diode lasers, they are made using semiconductor materials.
Widely used in telecommunications, barcode readers, and laser pointers.
Fiber Lasers
These lasers use optical fibers as the active medium, offering high power and excellent beam quality.
Used in industrial applications and telecommunications.
Applications of Lasers
Industrial and Manufacturing
Laser cutting, welding, marking, and engraving.
Material processing and micromachining.
Medical and Healthcare
Laser surgeries, including LASIK eye surgery.
Dermatology treatments and cosmetic procedures.
Communication and Information Technology
Optical fiber communication systems.
Data transmission and high-speed internet connections.
Optic Fibre
Definition and Function
Optical fiber is a thin, flexible, transparent, and cylindrical medium for transmitting light signals over long distances.
It consists of a core, cladding, and protective coating, allowing efficient transmission and minimal signal loss.
Types of Optic Fibres
Single-Mode Fiber
Has a small core diameter and only allows one mode of light to propagate.
Suitable for long-distance communication and high-speed applications.
Multi-Mode Fiber
Has a larger core diameter and supports multiple light propagation modes.
Used in shorter distance communication and lower bandwidth applications.
Advantages of Optic Fibre
High Bandwidth
Capable of transmitting large amounts of data at high speeds.
Enables faster internet connections and data transfer rates.
Immunity to Interference
Fiber optic signals are not affected by electromagnetic interference or radio frequency interference.
Provides reliable and secure data transmission.
Long Distance Transmission
Can transmit signals over long distances without significant degradation.
Used in intercontinental communication and submarine cable systems.
Applications of Optic Fibre
Telecommunications
Backbone networks and long-distance communication.
Fiber-to-the-home (FTTH) installations for high-speed internet.
Data Centers
Connect servers and storage systems within data centers.
Facilitate high-capacity data transfer and networking.
Medical Imaging
Endoscopy and minimally invasive surgeries.
Optical coherence tomography (OCT) for detailed imaging.
Sensing Applications
Distributed temperature and strain sensing.
Used in oil and gas industry, structural health monitoring, and environmental monitoring.
