Abstract

A (87)Rb hyperfine optical-pumping light source less than 4 cm long has been fabricated. Features of this new light source are: A 3-7-mm-long (85)Rb filter cell is attached to the front face of a cylindrical (87)Rb lamp with a diameter of 10mm, and both the lamp and the filter cell are operated at the same temperature of about 100 degrees C. A satisfactory spectral profile of D(1)-line output (lambda = 794.8 nm) has been observed by using a Fabry-Perot interferometer.

Composite-type Rb-87 optical-pumping light source for the rubidium frequency standard

N. Oura, Naimu Kuramochi, Shigeya Naritsuka +1 more

This paper describes the experimental results and theoretical analysis of a newly devised compact light source for the Rubidium Frequency Standard (RFS). The light source is composed of a cylindrical Rb-87 lamp 10 mm diameter and a Rb-85 filter cell 3-7 mm long attached to the front flat face of the lamp. This composite-type device is operated in an oven at about 100-deg C. Thus a light source for Rb-87 hyperfine optical pumping less than 4 cm long by 3 cm diameter has been constructed.

Spectral Profiles of the87Rb Pumping Light Source

Naimu Kuramochi, Hitohiro Fukuyo, Isao Matsuda +1 more

This paper is concerned with experimental studies of the 87 Rb pumping light source, which is composed of a 87 Rb lamp and a 85 Rb filter cell. Spectral profiles of the pumping light were observed by means of a Fabry-Perot interferometer. Measurements were executed by using ten filter cells which contained 85 Rb atoms and various gases (N 2 , Ar and He) under various pressures. As a result, it became clear that the change of the pumping light spectrum with the filter cell temperature was specific to each cell. When we took note of the ratio and the difference of the two components of Rb D 1 line as measures of the filtering effect, the temperature dependence of these values relied on the kind and the pressure of the foreign gas.

Analysis of the temperature dependence of ^87Rb lamp profiles

Naimu Kuramochi, Isao Matsuda, N. Oura +1 more

The temperature dependence of the spectral profile of the 87Rb D1 line (λ = 794.8 nm) observed by a Fabry-Perot interferometer has been discussed by considering the self-absorption mechanism in the lamp. The Rb lamp is assumed to be composed of two separated portions: One is a spherical core of emitting Rb atoms and the other is an outer layer of the same kind of absorbing atoms surrounding the core. The temperature dependence of the emitted light intensity, intensity difference between two hyperfine peaks, and asymmetry of the self-absorbed profiles are systematically explained in the temperature range of 75 to 125°C. The equivalent absorbing atom layer near the lamp surface is estimated to be 0.5 mm in this model.

Spectral Profiles of the87Rb D1Line Emitted from a Spherical Electrodeless Lamp

Naimu Kuramochi, Takayoshi Matsuo, Isao Matsuda +1 more

Spectral profiles of the 87 Rb D 1 line (λ=794.8 nm) are observed by a Fabry-Perot interferometer for a spherical electrodeless lamp (BBL type) which contains 2.8 Torr of Kr as a starting gas. Temperature dependence of the spectral profiles is measured and the characteristics of the observed profiles such as the intensity, width and self-absorption of each hyperfine component line are discussed. From the convolution calculation, the equivalent half widths are estimated to be 1.05 GHz for the e and the f lines and 1.25 GHz for the c and the d lines when the lamp surface temperature is 80°C.

Temperature Dependence of Hyperfine Spectrum of Rb D1Line

Hitohiro Fukuyo, Kenichi Iga, Naimu Kuramochi +1 more

This paper deals with the experimental studies of the rubidium (Rb) spectral lamp for the purpose of getting an excellent pumping light source for a Rb gas cell type frequency standard, or for a Rb microwave maser. Some of Rb lamps containing Ne, Ar, Kr, and Ne-Ar as a carrier gas were made by way of experiment. In order to observe the hyperfine spectrum of D1line, the Fabry-Perot type scanning interferometer was made, which is driven electrostrictively. The hyperfine components of D1line were resolved successfully. It was observed that the line which is used as a pumping source became intense as the lamp temperature was raised, and it began to be dipped and decrease, however, over the definite temperature. Also observed was that this optimum temperature differs from the temperature at which the integrated intensity of D1line shows a maximum.

Absorption of Rb-D Limes by Rb Filter Cell

Toshiharu Tako, Y. Koga, Isao Hirano +1 more

The effects of absorption of Rb-D lines are studied with the combination of natural Rb lamps and natural Rb filter cells containing nitrogen at the pressures of 100 Tori and 152 Torr. It is found that the hyperfine components of D lines effective for optical pumping is obtained with Rb atoms of natural abundance both for lamps and for cells. The optimum temperature of the filter cell is observed to be near at 60°C. The absorption coefficient of the filter cell is less than 1.5 cm -1 . The absorption cross sections obtained for three broad peaks consisting of hyper finecomponents are measured to be 10 -12 ∼10 -13 cm 2 , which is 10 2 ∼10 3 times larger than the atomic cross section of Rb in its ground state. The absorption cross sections for the filter cell with N 2 100 Torr have values a few times larger than those for the filter cell with N 2 152 Torr.
