    Dark resonance of Cs atoms velocity-selected in a thin cell

    We carried out experimental and theoretical research on dark Raman resonances in the absorption of the probe monochromatic wave in a thin vapor cell, whose length is much less than the diameters of probe and c...

    Allan-variance measurements of diode laser frequency-stabilized with a thin vapor cell

    A novel method of stabilizing laser frequency that uses a sub-Doppler spectrum of atoms in a thin vapor cell has been developed. The extended-cavity diode laser is frequency-locked to a hyperfine component of ...

    High-resolution spectroscopy of velocity-selected atoms in a thin cell

    We propose a novel technique of sub-Doppler spectroscopy using a thin vapor cell. Optical pum** in a thin cell transfers atoms with small velocity components to a specific quantum state. The resultant veloci...

    Measurement of rotational temperature in CO2 waveguide laser medium

    A small-signal gain in CO2 waveguide laser medium has been measured on rotational-vibrational transitions in the P-branch of the (0, 0, 1)-(0, 20, 0) band. It has been found that the rotational temperature is wel...

    Undamped undulation superposed on the passive Q-switching pulse of a CO2 laser

    An undamped undulation superposed on the pulse tail of the passive Q-switching is observed using HCOOH gas as a saturable absorber. The pulse shapes with the undulation are nicely reproduced through the rate-e...
