As shown in Figure 2, implement example for one as air gap etalon, first cylinder, the second cylinder optical cement are on same substrate, the other end respectively bonds a piece of partially reflecting mirror (i.e. Part I reflecting mirror 301, Part II reflecting mirror 302), and this pair reflecting mirror constitutes described air gap etalon.The height of two support tubes differs about 20 μm, and therefore, the Free Spectral Range of this etalon is about 60nm, and to ensure to select single longitudinal mode in laser optical spectral limit, outer layer cylinder have employed crystal expansion pipe in addition, and is accompanied by heating ring plate；Internal layer cylinder adopts zero expansion glass pipe.
As it is shown on figure 3, implement example as another of air gap etalon, two chamber mirrors of etalon (i.e. Part I reflecting mirror 301, Part II reflecting mirror 302) are not bonded on concentric drums, but by a column as supporter.
Although specifically showing in conjunction with preferred embodiment and describing the present invention; but those skilled in the art should be understood that; in the spirit and scope without departing from appended claims invention defined; in the form and details the present invention is made a variety of changes, be protection scope of the present invention.
