Description
Technical Field
The invention belongs to the technical field of laser application, and particularly relates to a device for generating a new substance by bombarding a target material with laser.
Background
Since the birth of the laser, the interaction between the laser and the substance becomes a durable hot research field, and the research of new materials and new substances is one of the basic research fields which have great influence on the progress of engineering technology. The generation of new materials or substances can be realized by various technologies, the target is bombarded by high-energy laser to generate new substances, and the method has the advantages of flexible use, simple process, strong repeatability, good mass production capacity and the like, and is one of the technological approaches with great prospect. For example, in the field of catalytic chemistry, high-energy laser is used for bombarding certain targets, so that certain macromolecular substances with large specific surface areas can be generated, and the high-energy laser has particularly good catalytic performance and can be used for efficiently producing certain industrial products.
The high-energy laser action and the target material can generate a large amount of heat, so that the temperature of the target material and generated substances is rapidly increased. If the environmental gas is chemically reactive, such as in the presence of oxygen, the generated substances will react chemically with the environmental gas. In order to avoid chemical reactions, it is common practice to use inert gases as protective gases. Furthermore, the temperature of the material produced by laser bombardment of the target material is generally high, and it is usually necessary to cool it first before measuring its properties. At present, the generated substances are cooled by adopting a heat conduction-based method, the cooling time is longer, and the cooling effect is poorer.

A quartz window is arranged at one end of the target material chamber, a laser focusing mirror is arranged below the quartz window, and an air inlet pipeline is arranged near the quartz window; the other end of the target material chamber is communicated with the substance detection chamber through the supersonic velocity spray pipe.

The supersonic velocity spray pipe 10 adopts a Laval spray pipe structure.
Furthermore, the device for generating the new substance by using the laser to bombard the target can use a plurality of substance detecting instruments to measure the generated substance.
Furthermore, in the device for generating the new substance by using the laser to bombard the target, the buffer gas is inert gas with inactive chemical property, and the generated substance reacts with gas with active chemical property such as ambient oxygen under the high-temperature condition.
