From being born from laser, the interaction of laser and substance is become for a unfailing hot research neck
Domain, and the research of new material and novel substance is one of the basic research field for having significant impact to engineering technology progress.It generates
New material or substance can be realized by multiple technologies, generate novel substance using superlaser bombardment target, have and use
Flexibly, the advantages that process is succinct, repeatability is strong, mass production capabilities are good, right and wrong are often with one of promising technological approaches.Example
Such as, in field of catalytic chemistry, certain targets are bombarded using superlaser, can produce some macromolecular complex of large specific surface area
Matter has particularly good catalytic performance, can be used for the efficient production of certain industrial products.
Superlaser effect can generate a large amount of heat with target, make the substance steep temperature rise of target and generation.If ring
The chemical activity of border gas is stronger, such as there are oxygen, then the substance generated can be made to chemically react with environmental gas.For
Avoid the generation of chemical reaction, it is common practice to use the inert gas as protective gas.Furthermore pass through laser bombardment target
The temperature for the substance that material generates is usually higher, it usually needs first cools down to it, then could measure to its property.
All the substance of generation is cooled down using the method based on heat transfer at present, cooling time is longer, and cooling effect is poor.
Summary of the invention
In view of the drawbacks of the prior art, the present invention provides a kind of device that novel substance is generated using laser bombardment target.
The technical solution adopted by the present invention are as follows:
A kind of device generating novel substance using laser bombardment target, including laser condensing lens, target room, supersonic speed spray
