The common fluorescent lamp is a low-pressure mercury arc lamp.
2.
Medium or low-pressure mercury arc lamps can excite these respective transitions.
3.
They produced it by irradiating a frozen mixture of mercury, oxygen and hydrogen with light from a mercury arc lamp.
4.
Raman employed monochromatic light from a mercury arc lamp which penetrated transparent material and was allowed to fall on a spectrograph to record its spectrum.
5.
Unlike the usual side-pumping method, the light from a mercury arc lamp was pumped into the end of a very small rod, to achieve the necessary population inversion.
6.
Several military laboratories, including those in the United States, continued R & D efforts on the photophone into the 1950s, experimenting with high-pressure vapour and mercury arc lamps of between 500 and 2, 000 watts power.
