“…[7][8][9][10] However, only the surface temperature rather than the internal temperature of the vapor cells can be sensed, and the internal temperature distribution is a controversial issue. [11][12][13][14][15][16] Optical thermometry is an approach that avoids the above-mentioned problems. [17][18][19][20] In particular, the Doppler effect can link thermal energy with atomic spectral lines to measure gas temperature.…”

We demonstrate an experimental method for the in situ temperature measurement of atomic vapor using saturated absorption spectrum. By separately manipulating the frequency of pump beam and probe beam, the position of crossover peaks can move along the spectrum. Different velocity classes of atoms contribute to the crossover during the movement. We study the relationship between the intensity change of peaks and vapor temperature. Our experimental result around room temperature shows a deviation of less than 0.3 K. Compared with traditional thermometry using absorption spectroscopy, higher accuracy can theoretically be achieved for real-time thermometry.

“…Their corresponding models were set up by [9][10][11][12][13][14][15] and agreed well with the experimental results. Additionally, in order to further improve the power of DPALs, researches on master oscillator power amplifier (MOPA) have also been conducted [16][17][18][19][20][21][22], demonstrating the high efficiency of DPALs and the potential for power scaling.…”
