Laser radiation being delivered via a fiber for photodynamic therapy to treat cancer. A 40-watt CO 2 laser with applications in ENT, gynecology, dermatology, oral surgery, and podiatry. Laser medicine is the use of lasers in medical diagnosis, treatments, or therapies, such as laser photodynamic therapy, [1] photorejuvenation, and laser surgery.
A TEA laser is a gas laser energized by a high-voltage electrical discharge in a gas mixture generally at or above atmospheric pressure. The most common types are carbon dioxide lasers and excimer lasers, both used extensively in industry and research; less common are nitrogen lasers. The acronym "TEA" stands for "transversely excited atmospheric".
RCTI is available as a free-to-air channel in East Timor, but only in Dili and other cities such as Ermera and Baucau. RCTI is also available in Malaysia as a free-to-air channel in Johor Bahru, and in Singapore as a free-to-air channel by using antenna. RCTI is the only Indonesian free-to-air TV channel to be broadcast free-to-air outside ...
Laser surgery is a type of surgery that cuts tissue using a laser in contrast to using a scalpel. [ 1 ] Soft-tissue laser surgery is used in a variety of applications in humans ( general surgery , neurosurgery , ENT , dentistry , orthodontics , [ 2 ] and oral and maxillofacial surgery ) as well as veterinary [ 3 ] surgical fields.
In a race, a laser scanner records the speed of the car at the end of its run. Often, the dragster is carved out of balsa wood because of its light weight and cheapness. [1] [2] CO 2 cars are a part of engineering curricula in parts of the world such as Australia, New Zealand [1] and the United States. [2]
Laser pumping is the act of energy transfer from an external source into the gain medium of a laser. The energy is absorbed in the medium, producing excited states in its atoms. When for a period of time the number of particles in one excited state exceeds the number of particles in the ground state or a less-excited state, population inversion ...
Photograph of a freestanding silicon disc being heated locally by a laser in a TLE chamber. [4]TLE uses continuous-wave lasers (typically with a wavelength of around 1000 nm) located outside the vacuum chamber to heat sources of material in order to generate a flux of vapor via evaporation or sublimation.

A carbon dioxide scrubber. A carbon dioxide scrubber is a piece of equipment that absorbs carbon dioxide (CO 2).It is used to treat exhaust gases from industrial plants or from exhaled air in life support systems such as rebreathers or in spacecraft, submersible craft or airtight chambers.
