Laser is a vigorous source of light having amazing properties which are not found in the usual light sources like mercury lamps, tungsten lamps etc. The special property of laser is that its light waves travel very long distances with a very slight divergence. A high nick of directionality and monochromatic nature is also associated with these light beams. The principle of a laser is based on three discrete features:
Stimulated emission within an amplifying medium
an optical resonator
population inversion of electronics
Optics is the study of light. We depend on optics every single day. Our wireless mouse, digital camera and even Blu-ray disc of your much-loved movie are all technologies empowered by the science of optics. More precisely, optics is a subdivision of physics describing how light behaves and interacts with matter. Optics is a vibrant and emerging field with a broad history.Three critical models are utilized to portray optical phenomena and each one is built up on, one of the three distinctive methods for defining Electro Magnetic Radiation.

In the present day laser world, the word “Pulse” covers pulse durations from microseconds (free-running laser) to tens of femtoseconds (mode-locked laser). It is possible to generate attosecond pulses (1as is 10-18 s) by means of non-linear processes. In recent times, a fresh time range was discussed in publications: zeptosecond (1zs is 10-21 s). To promote pulses from milliseconds to femtoseconds, hundreds of different laser systems have been developed. They can characteristically generate pulses of specific durations, which are due to laser principles of operation, parameters of gain medium, specific construction, kind of modulator, and so on.
In the solid-state free-running laser the constraints of the electromagnetic field interaction process with an inversed population of the gain medium play a dominant role in determining the laser spikes. These distinctive parameters limit the pulse duration from the long side of the range.

Solid-state lasers provide the most versatile radiation source in terms of output characteristics when compared to other laser systems. A large range of output parameters, such as average and peak power, pulse repetition rate, pulse width and wavelength, can be attained with these systems. Today we find solid-state lasers in industry as tools in many manufacturing processes, in hospitals and in doctors’ offices as radiation sources for therapeutic, aesthetic, and surgical procedures, in research facilities as part of the diagnostic instrumentation, and in military systems as rangefinders, target designators, and infrared countermeasure systems.

A laser diode is manufactured like a plane-paralleled rectangle where the two faces, perpendicularly split at the plane and where the releasing semi-conductors meet, form a Fabry-Perot resonator. The resonator is the origin of the emission stimulated by differentiating light emission photons.
Laser diodes vary from conventional lasers, in several ways.
Small size and weight: A characteristic laser diode measures less than one millimetre in size and weighs a fraction of a gram, creating it accurate for usage in portable electronic equipment.
Low voltage, current and power requirements: They can work by utilising small battery power supplies. Maximum laser diodes need some milliwatts of power at 3 to 12 volts DC and some milliamperes.
Low intensity: A laser diode can never be used for massive purposes such as bringing down satellites, burning holes in metal, or blind folding aircraft pilots. Though, its coherent output effects in high efficiency and easiness of modulation for communications and control applications.

Lasers have become an indispensable part of our lives with utilities in consumer electronics, communications, sensors, and medicine. Every single compact disc player contains semiconductor laser, and airplanes rely on laser gyroscopes for navigation. Lasers are used up for photocoagulation of the retina to stop retinal discharging and for the tacking of retinal tears. Apart from this laser suits application in the garment industry, surveying and ranging, barcode scanners. Around 50 years back, CU graduate Theodore Maiman (Engineering Physics '49) showcased the world's first working laser, that is the ruby laser at Hughes Research Laboratories in Malibu, California.
Medical Lasers: Medical lasers are exploited as a scalpel. Since the laser can be controlled and can have such a small contact area it is perfect for depth control and fine cutting. Medical lasers can likewise be utilized to reattach retinas and might be used in combination with fiber optics to place the laser beam where it needs to be. Medical lasers are applied to stitch up incisions after surgery, by fusing skin together.
Entertainment: Laser shows are quite famous and the special effects are bewildering. These make use of lasers that are in the visible range alongside vibrating mirrors to paint images in the air.
Metal working: Lasers permits improved cuts on metals and the welding of dissimilar metals without the use of a flux. Furthermore lasers can be fixed on robotic arms .This is safer then oxygen and acetylene, or arc welding.

The vivid deterioration of transmission loss in optical fibers coupled with equally important developments in the zone of detectors and light resources has brought about a phenomenal progress of the fiber optic industry during the previous two decades. The foundation of optical fiber communication overlapped with the fabrication of low-loss optical fibers and working of semiconductor lasers at room-temperature of in 1970. From that point onward, the scientific and technological progress in this arena has been so extraordinary that we are already in the fifth generation of optical fiber communication systems inside a fleeting range of 30 years.
New developments in optical amplifiers and wavelength division multiplexing (WDM) are appealing us to a communication system with approximately “zero” loss and “infinite” bandwidth. Indeed, optical fiber communication systems are gratifying the puffed-up demand on communication links, especially with the spread of the Internet. Optical Waveguides and Fibers, is an outline to the basics of fiber optics, discussing solely the characteristics of optical fibers as regards to their use in telecommunication and fiber optic sensors.

Nanomaterials are cornerstones of nanoscience and nanotechnology. Nanostructure science and technology is a broad and interdisciplinary area of research and development activity that has been growing explosively worldwide in the past few years.
One of the most fascinating and useful aspects of nanomaterials is their optical properties. Applications based on optical properties of nanomaterials include optical detector, laser, sensor, imaging, phosphor, display, solar cell, photocatalysis, photoelectrochemistry and biomedicine. The optical properties of nanomaterials depend on parameters such as feature size, shape, surface characteristics, and other variables including doping and interaction with the surrounding environment or other nanostructures.

Adaptive optics (AO) is the science, art and technology of catching diffraction-limited pictures in adverse circumstances that would usually lead to strongly degraded picture quality and loss of resolution. In non-military applications, it was first offered and implemented in astronomy. AO knowledge has since been applied in many disciplines, including vision science, where retinal quality down to a few microns can be resolved by correcting the aberrations of ocular optics.
The conventional principle of AO is to measure the irregularities introduced by the media between an object of interest and its image with a wavefront sensor, analyse the measurements, and calculate a correction with a control computer. The alterations are applied to a deformable mirror (DM) positioned in the optical path between the object and its image, thereby enabling high-resolution imaging of the object.

For lasers, the developments are quick and influential. Shorter pulse widths and more prominent force are future headings for the innovation. On the skyline are new lasing resources and fresh concepts to produce laser like light sources. The outcome of these growths could be more effective, less wasteful manufacturing as well as systems that consume less energy.
In current years, the U.S. has made plentiful developments in high-energy laser technology, producing a megawatt-class laser, with other small number of different nations not a long ways behind. Combining lasers with space-based relay mirrors could offer the competency of conveying a ground-based laser headed for any point on the earth, a ballistic missile or an orbiting satellite in aerospace. By the year 2035, various nations will likely have developed this ability, which will suggestively affect U.S. national security.
