A mercury spectrum lamp

Abstract

The invention discloses a mercury spectroscopic lamp. The mercury spectroscopic lamp comprises a bubble chamber and an excitation box. The excitation box comprises a signal feed-in unit used for transmitting microwave signals, and a radio frequency power amplifying transmission unit connected with the signal feed-in unit via a coaxial cable. The bubble chamber comprises a sapphire lighting bubble, a heater and a helical line. The helical line is wound on outer surface of the sapphire lighting bubble, connected with a wire of the output end of the radio frequency power amplifying transmission unit and used for providing microwave signals going through the radio frequency amplification for the sapphire lighting bubble. The heater is used for heating the sapphire lighting bubble. The sapphire lighting bubble is filled with mercury isotopes. When the heater heats the sapphire lighting bubble to a set temperature, mercury ions in the sapphire lighting bubble give out laser with the set wavelength under effects of microwave signals provided by the helical line. By use of the sapphire lighting bubble, contamination to the inner mercury ions caused by impurities and loss of the mercury ions can be greatly reduced or avoided in a working process and service lifetime of the mercury spectroscopic lamp is effective extended.

Description

technical field [0001] The invention relates to the field of spectrum lamps, in particular to a mercury spectrum lamp for obtaining mercury ion microwave frequency standards. Background technique [0002] Atomic frequency standards (also known as atomic clocks) are widely used in many fields such as positioning, navigation, communication, and military affairs. The atomic frequency standard acts on the corresponding atoms (such as rubidium, cesium, etc.) to cause the atoms to transition, so as to obtain the spectrum emitted by the atomic transition, and then further obtain the corresponding atomic frequency standard (ie, the atomic frequency standard) according to the spectrum. mark). [0003] At present, as a new type of atomic frequency standard, the mercury ion microwave frequency standard adopts a new working principle different from traditional atomic frequency standards such as hydrogen, rubidium, and cesium. Due to the characteristics of long state coherence time and...
