nitrogen laser

Meanwhile, a great white shark with what is described as a military nitrogen laser, approaches the island.

Measured nitrogen laser pulses are so long that the second step is unimportant.

The gas pressure in a nitrogen laser ranges from a few mbar to as much as several bar.

For similar reasons, pure molecular nitrogen lasers typically emit light in the ultraviolet range.

As examples, I think water-filled spark-gaps have been tried for things like Nitrogen lasers.

For electric discharge pump see: Nitrogen laser.

The nitrogen laser is a three-level laser.

Nitrogen lasers and excimer laser are used in pulsed dye laser pumping.

The transverse discharge nitrogen laser has long been a popular choice for amateur home construction, owing to its simple construction and simple gas handling.

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.

With matrix-assisted laser desorption electrospray ionization (MALDESI), a nitrogen laser is used to desorb material into the electrospray.

The wall-plug efficiency of the nitrogen laser is low, typically 0.1% or less, though nitrogen lasers with efficiency of up to 3% have been reported in the literature.

With about 11 ns the UV generation, ionisation, and electron capture are in a similar speed regime as the nitrogen laser pulse duration and thus as fast electric must be applied.

Helium-neon lasers require around a 99% reflective mirror to lase, while nitrogen lasers have an extremely high gain (they are "superradiant") and do not require any OC (0% reflective).

The availability of small and relatively inexpensive nitrogen lasers operating at 337 nm wavelength and the first commercial instruments introduced in the early 1990s brought MALDI to an increasing number of researchers.

Countering this argument is the fact that Tanaka was the first to use a 337 nm nitrogen laser while Karas and Hillenkamp were using a 266 nm Nd:YAG laser.

Then, a shark with what looks like a military nitrogen laser slowly lurks towards him, almost like Jaws, but before the shark gets its chance, Klak is caught by a giant octopus and is eaten alive.

MALDI techniques typically employ the use of UV lasers such as nitrogen lasers (337 nm) and frequency-tripled and quadrupled Nd:YAG lasers (355 nm and 266 nm respectively).

In a few situations it is possible to obtain lasing with only a single pass of EM radiation through the gain medium, and this produces a laser beam without any need for a resonant or reflective cavity (see for example nitrogen laser).

The breakthrough for large molecule laser desorption ionization came in 1987 when Koichi Tanaka of Shimadzu Corp. and his co-workers used what they called the "ultra fine metal plus liquid matrix method" that combined 30 nm cobalt particles in glycerol with a 337 nm nitrogen laser for ionization.
