Abstract
The utility model relates to a tuning-free solid laser, which solves such problems of a total reflection mirror and a partial reflection mirror as complex manufacturing techniques, difficult installation and adjustment, as well as high cost. The solid laser is characterized in that an assembly sleeve (4) is arranged in a seal cover (11); a light-focusing cavity (1) is formed in the assembly sleeve and penetrated by a laser crystal rod (2) and a pump source (3) which are axially parallel to each other; one end surface of the laser crystal rod (2) is plated with total reflection film to serve as a total reflection mirror on a light path; and the other end surface of the laser crystal rod (2) is opposite to a light outlet (10) on the wall of the seal cover, and is plated with partial reflection film to serve as a partial reflection mirror on the light path.
Description
Technical field:
The utility model is relevant with optical resonator of exempting from tuning solid state laser and laser crystal bar.
Background technology:
Laser crystal bar and optical resonator are the chief components of laser, and laser crystal bar is the stimulated luminescence material, and resonant cavity is that photon can vibrate repeatedly therein and has the optical cavity of frequency-selecting and modeling effect.
The optical resonator of traditional solid state laser is made up of separate completely reflecting mirror and partially reflecting mirror, and the depth of parallelism of two mirrors is great to the laser works performance impact, and installation and adjustment require very high.Relatively more responsive to vibrations and temperature, limited the extensive use of laser.
The utility model content:
The purpose of this utility model provides a kind of simple in structure, and is with low cost, installs and adjusts easily, to the solid state laser of vibrations and temperature-insensitive.
The utility model is achieved in that
The utility model is exempted from tuning solid state laser, assembling cover 4 is arranged in the seal closure 11, in the assembling cover laser pump cavity 1 is arranged, the laser crystal bar 2 and the pumping source 3 of axially parallel pass laser pump cavity 1, one end face of laser crystal bar 2 is coated with total reflection film as the completely reflecting mirror on the light path, the other end of laser crystal bar 2 is relative with light exit 10 on the seal closure wall, and this end face is coated with the partial reflection film as the partially reflecting mirror on the light path.
Laser pump cavity 1 is ceramic chamber or mirror metal chamber.
Pumping source 3 is lamp pump or semiconductor pump.
Inlet opening 5 and apopore 6 are arranged at assembling cover 4 bottoms, and electrode interface 9 is arranged on the seal closure 11.
The utility model replaces independently completely reflecting mirror and partially reflecting mirror at the both ends of the surface plating reflectance coating of laser crystal bar.Laser crystal bar and speculum are integrated in one, and be simple in structure, the formation of speculum with finish with being connected once of laser crystal bar, manufacturing process is simple, and is with low cost.Avoided the parallel and coaxial adjusting problem between two speculums,, enlarged the range of application of laser vibrations and temperature-insensitive with laser crystal bar.
Description of drawings:
Fig. 1 is a structure chart of the present utility model.
Embodiment:
Have on one lateral sidewalls of seal closure 11 on two electrode interface 9, one longitudinal side walls light exit 10 is arranged.The seal closure bottom transverse is provided with assembling cover 4.Inlet opening 5 and apopore 6 are arranged at the bottom of assembling cover 4.In the assembling cover 4 laser pump cavity 1 is arranged.Laser pump cavity 1 is earthenware or mirror metal pipe.Upper and lower laser crystal bar that is arranged in parallel 2 and pumping source 3 are arranged in the laser pump cavity 1.The total reflection film of an end face plating applicable wavelengths of laser crystal bar, the partial reflection film of another end face plating applicable wavelengths, pumping source 3 is lamp pump or semiconductor pump.
