Absolute frequency metrology of buffer-gas-cooled molecular spectra at 1 kHz accuracy level

Autor: Roberto Aiello, Valentina Di Sarno, Maria Giulia Delli Santi, Maurizio De Rosa, Iolanda Ricciardi, Paolo De Natale, Luigi Santamaria, Giovanni Giusfredi, Pasquale Maddaloni

Publikováno v: Nature Communications, Vol 13, Iss 1, Pp 1-7 (2022)

High-resolution molecular spectroscopy with cryogenic setups is hampered by the lack of a skilled interrogation tool. Here, the authors demonstrate absolute metrology of cold rovibrational spectra at 1 kHz accuracy level, by coupling a Lamb-dip satur

Absolute frequency metrology of buffer-gas-cooled molecular spectra at the 10-12 accuracy level

Autor: Roberto Aiello, Valentina Di Sarno, Maria Delli Santi, Maurizio De Rosa, Iolanda Ricciardi, Paolo De Natale, Giovanni Giusfredi, Luigi Santamaria Amato, Pasquale Maddaloni

By reducing both the internal and translational temperature of any species down to a few kelvins, the buffer-gas-cooling (BGC) technique has the potential to dramatically improve the quality of ro-vibrational molecular spectra, thus offering unique o
