Typical Devices
The gas pressure in a nitrogen laser ranges from a few mbar to as much as several bar. Furthermore, air provides significantly less output energy than pure nitrogen or a mixture of nitrogen and helium. The pulse energy ranges from µJ to mJ (a commercial version using a spark gap delivers 300 microJ) and a peak power in the range of kW to more than 3 MW can be achieved. The pulse temporal width is between a few hundred picoseconds (typically at 1 atmosphere partial pressure of nitrogen) and a maximum of approximately 30 nanoseconds at reduced pressure (typically some dozens of Torr), though fwhm pulsewidths of 6 to 8 ns are typical.

Famous quotes containing the words typical and/or devices:
“Consciousness is cerebral celebrity—nothing more and nothing less. Those contents are conscious that persevere, that monopolize resources long enough to achieve certain typical and “symptomatic” effects—on memory, on the control of behavior and so forth.”
—Daniel Clement Dennett (b. 1942)
“The gods being always close to men perceive those who afflict others with unjust devices and do not fear the wrath of heaven.”
—Hesiod (c. 8th century B.C.)
