A method is disclosed for increasing an intensity of a signal detected in a spectroscopy device using a vapor cell and a spectroscopy device using the same. An operation method of the spectroscopy device may include: causing a first light for exciting an atom trapped in a vapor cell in a first hyperfine ground state to a first excited state to be incident on the vapor cell; causing a second light for exciting an atom trapped in the vapor cell in a second hyperfine ground state to a second excited state to be incident on the vapor cell; causing a third light for exciting the atom in the second excited state to a third excited state to be incident on the vapor cell; and detecting fluorescence which is emitted while the atom in the third excited state returns to the ground state.

An embodiment of the inventive concept provides a physics module of a chip-scale atomic clock. The physics module includes: a housing; a laser source disposed in the housing and generating a laser beam; a vapor cell disposed above the laser source to generate a transmitted beam from the laser beam; and a detector disposed above the vapor cell to detect the transmitted beam. Here, the vapor cell may include a plurality of optical patterns configured to polarize the laser beam.
