Problems solved by technology

[0004] Based on the above research results, it is found that the transfer efficiency of the xenon lamp to the surface of the gain medium is still low. This is mainly because: the understanding of the xenon lamp luminescence model is not sufficient, and the existing optimal design structure is to make full use of the light in the two-dimensional plane of the xenon lamp. But ignoring the light in other dimensions of space, the improvement range is limited, which not only causes a great waste of xenon lamp radiation energy, but also makes it difficult to achieve a uniform distribution of xenon lamp intensity on the surface of the gain medium

Abstract

Disclosed is a structure capable of improving light transmission efficiency and distribution uniformity of a xenon lamp. The structure comprises xenon lamps, reflectors, reflective sheets, multiple pieces of gain mediums, an upper reflective plate and a lower reflective plate; the structure is characterized in that the reflective sheets are added between the xenon lamps and the reflectors in the cross section direction of the xenon lamps; the reflective sheets are arranged in the axis direction of the xenon lamps; and the number of the reflective sheets is N, wherein N is greater than or equal to 2. The structure is simple and easy to implement, creative in idea, and capable of improving the transmission efficiency of light rays from the xenon lamps to the surfaces of the gain mediums, lowering energy supply, saving cost and improving the light intensity distribution uniformity of light rays on the surfaces of the gain mediums.

Description

technical field [0001] The invention relates to an amplifier, in particular to a structure used in a high-power laser device to improve the transfer efficiency and distribution uniformity of a xenon lamp from a chip amplifier to the surface of a gain medium. Background technique [0002] As the reflector of the coupler between the xenon lamp and the gain medium, its function is to transmit the light from the back of the xenon lamp to the surface of the gain medium. By optimizing the structure of the reflector, the self-absorption of the light by the xenon lamp and the mutual absorption between the xenon lamps are reduced. Increase the transmission efficiency of light, increase the energy deposition on the surface of the gain medium, and reduce the load of the xenon lamp. [0003] At present, reflectors of various shapes have been designed based on different understandings of luminescence models and different pumping methods at home and abroad. According to the imaging and p...
