Nitrogen laser

Nitrogen laser

A nitrogen laser is a type of gas laser that uses molecular nitrogen as its gain medium and is pumped by an electrical discharge. It operates in the ultraviolet range, typically emitting at a wavelength of 337.1 nm. It is also known as a transversely excited atmospheric (TEA) laser and is used as an irradiation source in various applications.From: Introduction to Laser Science and Engineering [2019], Soy-based, tannin-modified plywood adhesives [2018], Labs on Chip [2019], An Introduction to Biomedical Optics [2019]

The nitrogen laser is a transversely excited atmospheric (TEA) laser that operates in the ultraviolet at 337.1 nm. It is likely one of the most commonly “homebuilt” or “do-it-yourself” laser due to an article published in Scientific American in 1974, explaining how to build one with amateur construction techniques and materials from a local hardware store or hobby shop.

The potential efficiency of this laser measured in terms of energy lost by the electron beam in the gas and the stored energy is about 5% and is higher than for the argon–nitrogen laser. However, in a practical system this is off-set by the difficulty of coupling energy from a relativistic electron beam into a light gas with low stopping power.

The spectra were recorded on a SHIMADZU AXIMA Performance matrix-assisted laser desorption ionization (MALDI) instrument (Manchester, UK). The irradiation source was a pulsed nitrogen laser with a wavelength of 337 nm. The length of one laser pulse was 3 ns. The measurements were carried out using the following conditions: polarity (positive), flight path (linear), mass (high) (20 kV acceleration voltage), 100–150 pulses per spectrum. The delayed extraction technique was used applying delay times of 200–800 ns.
