Abstract

A new controllable cryogenic cell is designed to provide very useful low temperature spectroscopic parameters for a laser atmospheric transmission project and trace gas detection. On the basis of the existing low temperature cryogenic cell

the new developed cryogenic cell improves the installation of a dewar and a sample cell

cell sample materials and concrete cooling method

and increases temperature stability and uniformity of the cell. The experimental results indicate that the new cryogenic cell shows its temperature fluctuations to be less than ±0.3 K in monitoring time of 0.5 h and the temperature gradient to be about 0.03 K/cm. Based on the developed cryogenic cell

the low temperature spectroscopy of carbon dioxide at 6 358.654 cm

-1

is measured by using tunable diode laser absorption spectroscopy and the self-broadening coefficient and the temperature-dependent exponent (

=0.738±0.014) of the carbon dioxide absorption spectrum are obtained. The results show that the temperature-dependent exponent is in good agreement with that other reports. In conclusion

the cell is able to fulfill the requirements of low temperature absorption spectral experiments of atmospheric molecules.
