Embodiment Construction

[0027] see figure 1 , figure 2 .

[0028] figure 1 As shown in , there is medium B on the periphery of medium A, and medium A and medium B penetrate into each other through the mutual penetration of molecules to form a seamlessly integrated whole; figure 2 As shown in , three pieces of media B, A, and B form a whole in turn. Described medium A, B are selected from one of following:

[0029] (1) Doped laser crystals, such as Nd:YAG, Cr:YAG, Nd:GGG, Yb:GGG;

[0030] (2), undoped crystals, such as YAG, GGG, GdVO 4 、YVO 4 , KTP;

[0031] (3) Doped laser glass, such as neodymium glass;

[0032] (4) Undoped glass, such as ordinary optical glass.

[0033] Media A and B may be the same or different.

[0034] The preparation method is as follows:

[0035] The bonding planes of media A and B to be bonded are processed flat and smooth, and the smoothness of the bonding planes is above the optical level two, until an ultra-smooth plane; the flatness is zero aperture, that is,...

Abstract

This invention discloses a polygonal hot bonded compound laser medium and its making method. The polygonal hot bonded compound laser medium is seamless integrity composed of two or several blocks of medium, the medium is chosen from laser crystal, such as Nd:YAG, Cr: YAG, Nd:GGG, Yd:GGG, the laser glass, such as Nd glass; flatten and polish the connecting surface of the two or several same or different mediums, carry out optical agglutination and press tightly, increase the temperature slowly to the proper temperature, maintain the temperature for a while, and decrease the temperature to room temperature, and realize the permanent bonding between the mediums. Through the improvement of the performance of the laser medium, it can meet the demand of the fast development of highly efficient laser.

Description

technical field [0001] The invention relates to the field of optics, in particular to a method for preparing a polygonal heat-bonded composite laser medium. technical background [0002] The laser working substance is the core component of the laser. A working substance is a material capable of producing stimulated radiation. [0003] The traditional laser working material element is a single whole of the same single crystal or glass, without any processing machinery, optics, chemical processing and treatment inside the single crystal or glass, which is defined as a single laser working material, such as Nd:YAG rod, Nd :YAG thin plate, Nd:YAG slats, neodymium glass, etc. [0004] With the development of high-power lasers, this working substance is limited by heat dissipation, stress, size, etc., which limit the laser power and beam quality. Contents of the invention [0005] The present invention designs a new type of laser working substance, which is no longer a single...
