"Light Amplification by Stimulated Emission of Radiation," or "laser system," is a high-tech device that produces powerful, finely focused light beams. It works on the basis of stimulated emission, which is the process of exciting atoms or molecules to release coherent, synchronised photons. This produces a high-energy, narrow, monochromatic laser beam. Several industries use laser systems extensively, including manufacturing (for cutting, welding, and engraving), healthcare (for surgery and diagnostics), communications (for fibre optics), entertainment (for laser shows), research (for spectroscopy and microscopy), and defence (for targeting and rangefinding). They are essential instruments in contemporary science and technology because of their efficiency, accuracy, and adaptability.
High-intensity laser beams are used in the laser ablation of polymers method to precisely remove or etch polymer materials. This method is widely applied in many different fields, including electronics, biomedical devices, and micro manufacturing. Material is removed when the strong laser light is absorbed by the polymer's surface, leading to localised heating and vaporisation. It lowers the possibility of contamination or harm by enabling complex patterning, micro structuring, and surface modification of polymers without physical touch. Because different types of lasers (UV, IR, femtosecond, etc.) give different degrees of control and precision, laser ablation is a flexible tool for customised polymer processing in both industry and research.
Lasers and optics are essential to contemporary medicine. Internal organs and tissues may be seen non-invasively thanks to optical technologies like endoscopy and microscopy. Several medical specialties, such as surgery, dermatology, and ophthalmology, use lasers. They provide accurate tissue cutting, coagulation, and ablation while causing the least amount of harm to nearby healthy tissue. Skin problems, tattoo removal, and eyesight correction (LASIK) are among the conditions that laser therapy is used for. Moreover, optical imaging methods such as optical coherence tomography (OCT) help in tissue structure evaluation and eye disease diagnosis. In order to improve patient care, medical research, diagnostics, and treatments are still being advanced using optics and lasers.
The study and use of systems and devices that interact with both light (optical) and electricity (electronic) is the focus of the electronics field known as optoelectronics. It includes several different technologies, such as laser diodes, optical fibres, photodetectors, and light-emitting diodes (LEDs). Optoelectronic devices are essential for many applications, including displays, sensing technologies (found in cameras and barcode scanners), data transport via optical fibres, and even medical imaging devices like MRI machines. They are essential to modern technology and telecommunications because they fill the gap between optics and electronics and allow light signals to be converted, manipulated, and controlled.
When data is transmitted across optical fibres utilising optical signals, or light, it is referred to as optical networking or communications. This technology is essential to contemporary telecommunications because it provides dependable, secure, and fast data delivery. Optical fibres enable large bandwidth and long-distance communication by transmitting data as light pulses. Optical networks facilitate phone, video, and internet services by effectively directing data through switches and routers. New technologies such as fiber-to-the-home (FTTH) give homes access to fast internet. The globe is connected thanks in large part to optical communication, which enables local networks as well as international internet traffic, completely changing the way people exchange information and communicates.
Many industries have seen a change due to advancements in photonics. Faster and more effective data transmission in telecommunications is made possible by the miniaturisation and integration of photonic components, which will support 5G and beyond. With non-invasive diagnostic methods like optical coherence tomography (OCT) and precision laser surgery, photonics has completely changed the healthcare industry. In order to enable secure communication and quantum computation, quantum photonics investigates the quantum characteristics of light. The goal of green photonics is to produce energy sustainably with LEDs and solar cells. Photonic devices can be customised and made more reasonably priced via 3D printing. The future of technology and research will be shaped by ongoing advancements in materials, such as metasurfaces and nanophotonics, which hold promise for breakthroughs in sensing, imaging, and optical computing.
Light-matter interactions at the nanoscale are studied in the discipline of Nanophotonics. By utilising nanostructures to manipulate and control light, it makes advancements possible in fields such as sophisticated sensors, high-resolution imaging, and ultra-compact optical systems. Applications for quantum computing, data storage, and telecommunications exist in nano photonics.
Applied photonics technologies to biology and medicine is the emphasis of bio photonics.

Optical fibres are long-range light-pulse transmission devices made of thin, flexible glass or plastic strands. Their operation is predicated on the concept of total internal reflection, which holds that light waves are contained inside the fiber's core. Optical fibres are essential for data networks, internet connections, and telecommunications because they provide fast, secure, and low-loss data transfer. They make it possible to stream HD video, make long-distance conversations, and access the internet at higher speeds. Moreover, optical fibres are essential for laser, sensor, and medical endoscopic applications. They are an essential part of the infrastructure for modern communication and technology because of their enormous bandwidth and low signal attenuation.
Surface-enhanced spectroscopy is a potent analytical technique that increases the sensitivity of several spectroscopic techniques by multiple orders of magnitude, including infrared and Raman spectroscopy. It entails applying a sample—typically molecules or nanoparticles—to substrates, which are roughened surfaces or specially designed nanostructures. The interaction of light with these substrates produces strong electromagnetic fields at their surface, which significantly enhance the spectroscopic signals of nearby molecules. This makes it useful in domains including chemistry, biology, and materials science for applications ranging from chemical analysis to illness diagnosis and nanomaterial characterisation. It also makes it possible to detect tiny levels of chemicals.
