Over the last years, the laser has established its position as universal tool more and more; e.g. lasers are used in the fields of materials processing, medicine, communication and measuring technology. As cross-section technology and innovation driver laser technology not only serves photonics but also other industries.

Displaying this wide range of applications in industry and research, Laser Technology is one the most important activity fields of the Photonics Cluster Berlin-Brandenburg. The key to the success of the region is the strong research environment with its close connections to local industry. Thus, during the last years, in the capital region, a variety of network structures has been established, providing companies and research institutions access to resources, as knowledge and capital, at both local and international level. Moreover, companies often are market leaders in niche areas, which is an additional strength of the industrial Berlin-Brandenburg.

Laser security is the secure plan, utilize and usage of lasers to play down the chance of laser mishaps, particularly those including eye wounds. Since indeed moderately little sums of laser light can lead to lasting eye wounds, the deal and utilization of lasers is regularly subject to government regulations. Moderate and high-power lasers are possibly unsafe since they can burn the retina of the eye, or indeed the skin. To control the hazard of damage, different determinations, for illustration 21 Code of Government Controls (CFR) Portion 1040 in the US and IEC 60825 globally, characterize "classes" of laser depending on their control and wavelength. These directions force upon producers required security measures, such as labeling lasers with particular notices, and wearing laser security goggles when working lasers. Agreement benchmarks, such as American National Measures Established (ANSI) Z136, give clients with control measures for laser dangers, as well as different tables accommodating in.

Fiber lasers are rudimentary different from other laser types; in a fiber laser, the active medium that engenders the laser beam is genuinely isolated within the fiber optic itself. This discriminates them from fiber-distributed lasers where the beam is merely conveyed from the laser resonator to the beam distribution optics. Fiber lasers are now prominent because of its most focusable or highest effulgence of any laser type. The essentially scalable concept of fiber lasers has been used to scale multimode fiber lasers up to the output power more preponderant than 50 kW and single-mode fiber lasers capable of 10kW in puissance. Optical imaging is an imaging technique that customarily describes the comportment of visible, ultraviolet, and infrared light utilized in imaging. Since light is an electromagnetic wave, kindred portents occur in X-rays, microwaves, radio waves.

There are some surgical operations that are perplexing to perform with the conventional scalpel. Initial tribulations with laser beam showed that a finely focused beam from a carbon dioxide gas laser could cut through human tissue effortlessly and orderly. The surgeon could direct the beam from any angle by utilizing a mirror affixed on a movable metal arm. Consequently, now a day’s laser beam is the most desirable implement which is utilized as a standby for the conventional blade to perform arduous surgeries. Lasers were considered as most efficacious in operating on components that are facile to reach areas on the body's exterior, including the auditory perceivers, skin, mouth, ocular perceivers and nasal discerner. But in recent years medicos have established the remarkable progress in emerging laser techniques for use in internal exploration and surgery. For illustration, lasers are gradually used to emaculate plaque from people's arteries.

Traditional optics is isolated into two principle branches: geometrical (or beam) optics and physical (or wave) optics. In geometrical optics, light is considered to go in straight lines, while in physical optics, light is considered as an electromagnetic wave.

Geometrical optics can be seen as an estimate of physical optics that applies when the wavelength of the light utilized is substantially littler than the extent of the optical components in the framework being demonstrated.

In physical optics, light is considered to engender as a wave. This model predicts wonders, for example, obstruction and diffraction, which are not clarified by geometric optics. The speed of light waves in air is roughly 3.0×108 m/s (precisely 299,792,458 m/s in a vacuum). The wavelength of obvious light waves differs in the vicinity of 400 and 700 nm, however, the expression "light" is additionally regularly connected to infrared (0.7– 300 μm) and bright radiation (10– 400 nm).

Geometrical optics. Our day to day trip with light suggests that it travels, for the most part, in straight lines. When the sun’s rays peek thru a gap in a cloud or through a hole in some darkish foliage, we see non-stop ‘line’ or ‘stream’ of light rising from that gap. If we make the gap smaller (within limits, mentioned below), the stream gets narrower, however remains a circulation of light. 

  • Propagate in straight-line paths as they journey in a homogeneous medium
  • Bend, and in precise instances may break up in two, at the interface between two varied media
  • Follow curved paths in a medium in which the refractive index changes
  • May be absorbed or reflected. 

Present day optics incorporate the territories of optical science and designing that wound up plainly famous in the twentieth century. These territories of optical science regularly identify with the electromagnetic or quantum properties of light yet do incorporate different points. A noteworthy subfield of present-day optics, quantum optics, manages particularly quantum mechanical properties of light. Quantum optics isn't simply hypothetical; some cutting-edge gadgets, for example, lasers, have standards of operation that rely upon quantum mechanics. Light locators, for example, photomultipliers and channeltrons, react to singular photons. Electronic picture sensors, for example, CCDs, show shot commotion relating to the measurements of individual photon occasions. Light-radiating diodes and photovoltaic cells, as well, can't be comprehended without quantum mechanics. In the investigation of these gadgets, quantum optics regularly covers with quantum hardware.

Surface-enhanced Raman scattering (SERS) or Surface-enhanced Raman spectroscopy is a surface sensitive technique which enhances Raman scattering by the molecules adsorbed on the rough metal surfaces or by the nanostructures such as plasmonic magnetic silica nanotubes and the enhancement factor can be as much as 1010 to 1011, which means the technique may detect single molecules. The mechanism of enhancement effect of SERS is a matter of debate in the literature. There are two primary theories and their mechanisms differ substantially, distinguishing them experimentally has not been forthright. The electromagnetic theory recommends the excitation of localized surface plasmons, and then the chemical theory recommends the formation of charge transfer complexes. The chemical theory applies only to the species that have formed a chemical bond with the surface. So it cannot explain the observed signal enhancement in all the cases, whereas electromagnetic theory can put on even in those cases where the specimen is physisorbed only to the surface. It has been shown lately that SERS enhancement can occur even when the excited molecule is relatively far apart from the surface in which swarms of metallic nanoparticles enabling surface plasmon phenomena.
