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:
“It is indeed typical that you Earth people refuse to believe in the superiority of any world but your own. Children looking into a magnifying glass, imagining the image you see is the image of your true size.”
—Franklin Coen. Joseph Newman. The Monitor (Douglas Spencer)
“Soon silence will have passed into legend. Man has turned his back on silence. Day after day he invents machines and devices that increase noise and distract humanity from the essence of life, contemplation, meditation.... Tooting, howling, screeching, booming, crashing, whistling, grinding, and trilling bolster his ego. His anxiety subsides. His inhuman void spreads monstrously like a gray vegetation.”
—Jean Arp (1887–1948)
