The handpiece for treating the skin with irradiation using a light beam (F), comprises a first window () and a second window () and first means for cooling the first window (). Said first window () and said second window () are positioned opposite one another and are separated by a gas-filled space. They are capable of transmitting a light beam (F) and said first window () is intended to be applied in contact with the skin during the treatment. The handpiece comprises means for heating the gas between the two windows ().

A frequency-stabilized laser source that is adapted for use as a frequency standard. The frequency of the laser source is locked and the laser beam delivered by the laser source on a transition of an absorber chemical element. The technique combines both operation with saturated absorption and synchronous detection, based on modulating said transition being saturated by the beam passing through the absorber chemical element. This produces a single frequency laser beam whose output frequency is stationary. The frequency is not continuously modulated and is more precise than that which would be obtained operating with single-pass absorption only. The laser source is thus adapted for making a frequency standard.
