“…For our measurements, the cold finger was always kept at 20°C, which corresponded to an iodine vapor pressure of 0.27 mbar [22]. The cell itself was heated at 400°C to allow for enough population of the lower level of the 716 nm R903-10 transition that lies at 2372 cm −1 above ground state [13,21].…”

We report on the hyperfine-structure splitting of the 716 nm R903-10 molecular iodine transition. We show that this particular iodine line provides a very useful frequency reference in the context of a laser cooling experiment of iron atoms, an atomic species that has so far never been laser cooled and trapped to our knowledge. We provide experimental values for the hyperfine constants ΔeQq and ΔC of the investigated iodine transition. Dispersive signals of this transition are also presented and used to lock the frequency of a Ti:sapphire laser. The reported stabilization performance is fully compatible with the requirements of a laser cooling experiment of iron atoms.

“…Molecular iodine has a Doppler-broadened line listed at 13957.854250 cm −1 [15]. Considering the rovibronic level parameters of Gerstenkorn and Luc [21], this line identifies to the B 3 Π 0u ←X 1 Σ g R903-10 transition. Its wavenumber exceeds the sought wavenumber only by 0.009755 cm −1 , that is by 290(170) MHz.…”

“…We propose a new Doppler lidar using two slopes of one iodine absorption line [14][15][16][17] . This technique is based on the single edge technique using an iodine filter proposed by Friedman et al The iodine molecular has many absorption lines near 532nm which could be covered in wavelength by the second harmonic wavelength of Nd:YAG laser.…”

Incoherent Doppler lidar using two wavelengths for wind measurement

A new incoherent Doppler lidar technique for atmospheric wind measurement is presented. This direct detection Doppler lidar is realized by the transmitting laser with two wavelengths and the receiving system with only one bandpass or absorption filter. We fabricated actually the Doppler lidar system using the frequency doubled Nd:YAG laser which was alternately tuned to the both slopes of one absorption line of the molecular iodine with an AO wavelength shifter, and performed simultaneous measurements of the eastward and northward wind components from 8 to 25km altitude with 500m vertical resolution. This Doppler lidar system is very useful to measure the wind profiles between lower troposphere and stratosphere by one effort.

The incoherent Doppler lidar technique using the frequency doubled Nd:YAG laser which was alternately tuned to the both slopes of one absorption line of the molecular iodine was developed and wind measurements were observed from 8 to 25km with 500m range resolution. Owing to the evaluation of measurement accuracy of this Doppler lidar, the truth of the zero wind is confirmed by using the direct reflection light from the hard target and the standard deviation is 0.35m/s. The comparison observations between the lidar wind velocities and the wind profiles of a wind profiler are performed experimentally.
