Track 01 : Laser System

A laser is a device that uses energy to transmit light at specified wavelengths and amplifies that light by generating a very narrow beam of radiation. Light is an electromagnetic wave, as we all know. Each wave has its own brightness and colour, and polarisation shivers at a specific place. "Light enhancement by fortified emissions of radiation" is what laser stands for. When electrons in molecules in glassware, jewels, or gases retain vitality from an electrical current or another laser, they get "stimulated" and form a laser. The energized electrons exchange from a lower-energy circle to a higher-energy circle around the atom’s core. White light encases all colors within the range, but indeed a coloured light, such as a ruddy Driven contains a frequented interim of ruddy wavelengths. Laser is called continuous-wave.

Track 02 : Optics and Lasers in Medicine

The use of lasers in medical diagnosis, treatments, or therapies, such as PDT, is known as laser medicine.  After light activation, photodynamic therapy (PDT) is a two-stage treatment that combines light energy with a medication (photosensitizer) to kill malignant and precancerous cells. Initial laser beam tests revealed that a precisely focused beam from a carbon dioxide gas laser could effortlessly and skillfully cut through human flesh. As a result, the beam is the ideal equipment for performing difficult surgeries as a backup to the traditional blade. Lasers were thought to be most effective in working on portions of the body that are easy to reach, such as the ears, skin, lips, eyes, and nose.

The subject of nano-optics benefits from the convergence of advances in fundamental physics, particularly quantum optics, classical and micro-optics, and enhanced fabrication technologies. In contrast to mainstream nanotechnology, the prefix "nano" for optics does not always imply the use of nanometer-scale structures, where smaller is always better; the designation is frequently used for optical systems with sizes shorter wavelength, and thus is sometimes referred to as subwavelength optics. We'll look at micro- and nano-optical concepts with size scales ranging from a few micrometres to a few nanometers; we'll concentrate on devices rather than fundamental physical effects, which come in a wide range.Micro-optics are optical systems with a size ranging from a few micrometres to a millimetre. Small lenses or arrays of lenses, as well as optical fibres with a microscale core diameter, fall under this category. Integrated optics requires such small optical components. Traditional angle measurement tools such as Micro Optic Theodolites are used in geodesic survey and engineering measurement.
