Is there such thing as a nitrogen fueled laser?
A nitrogen laser is a gas laser operating in the ultraviolet range (typically 337.1 nm) using molecular nitrogen as its gain medium, pumped by an electrical discharge.
What is a nitrogen laser used for?
For many years, nitrogen lasers were used to pump dye lasers and as sources for many other applications requiring UV radiation. It is well suited to UV laser-induced fluorescence applications in clinical, pharmaceutical, environmental, and process-control work.
Which dye is used in laser?
Chemicals used Some of the laser dyes are rhodamine (orange, 540–680 nm), fluorescein (green, 530–560 nm), coumarin (blue 490–620 nm), stilbene (violet 410–480 nm), umbelliferone (blue, 450–470 nm), tetracene, malachite green, and others.
How does nitrogen laser work?
Working of Nitrogen laser Nitrogen molecule falls from energy level E3 energy level E2 ( called lower laser level LLL ) by emitting a photon of ultraviolet light of wavelength 337.1 nm. The nitrogen molecule then Falls from energy level E2 to the ground state and Laser action stops.
Which laser is used in CD player?
A Blu-Ray player uses blue laser light to probe the bumps and pits of the disc and a CD player uses red laser light. The relatively short-wavelength blue light is necessary to probe the smaller pits and bumps on a Blu-ray disc; smaller pits and bumps correspond to higher storage densities.
What does TEA laser stand for?
Transversely Excited Atmospheric
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 acronym “TEA” stands for Transversely Excited Atmospheric.
What are the advantages and disadvantages of nitrogen?
1) Nitrogen reduces the running temperature of your tyre. 2) Nitrogen is more stable than oxygen. When compared with oxygen inflated tyres, the rise in temperatures during the heat cycle remains moderate in nitrogen inflated tyres.
What is liquid dye laser?
Liquid lasers are those lasers which uses liquid as an active medium. In dye laser the liquid material called dye (for example rhodamine B, sodium fluoresein and rhodamie 6G) uses as an active medium, which causes to produce laser light.
What is TEA laser?
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.
Which laser is used in DVD?
Semiconductor diode lasers are used in CDs and DVDs..!
What laser is used in DVD?
Current DVDs employ a 650-nanometer red laser and have a recording capacity of 4.7 Gbytes. The Blu-ray Disc’s 405-nm blue-violet laser enables the recording and rewriting of up to 27 Gbytes of data.
