Description
The technical field is as follows:
the invention belongs to the technical field of laser, and relates to a laser propulsion method for graphene in thin gas.
Background art:
since the concept of solar sail is proposed, the light radiation propulsion has attracted great interest to the scientific community and the public, and the greatest advantage of the radiation pressure (light pressure) propulsion is that no additional fuel or energy is needed to be carried, so long as the light is irradiated; but the biggest disadvantage is that the radiation pressure is extremely small, and the strong radiation thrust is difficult to generate, thereby limiting the practical application of the radiation thrust. Until now, the laser ablation propulsion technology has attracted attention at the end of the 20 th century, and the basic principle is that an ablation substance (target) is heated under laser irradiation to generate high-temperature plasma, and the high-temperature plasma is ejected along the direction opposite to the incident direction of a light beam to generate a propulsion force. So far, macro sightseeing propulsion technology with large thrust without additional fuel carrying is not reported.
The invention content is as follows:
the invention aims to overcome the defects in the prior art, designs and provides a graphene laser propulsion technology in a thin gas, and can realize laser propulsion of a graphene material and related objects thereof in the thin gas.
In order to achieve the purpose, the specific process of the invention is as follows: placing the graphene material at an air pressure of not more than 103And in the Pa rarefied gas, irradiating the graphene material in the rarefied gas by using a laser beam to realize laser propulsion of the graphene material in the rarefied gas.
The rarefied gas of the present invention includes, but is not limited to, air, argon or nitrogen.
The graphene material provided by the invention has the size of nano-scale, micron-scale, millimeter-scale, centimeter-scale or meter-scale.
The quality and volume of the graphene material are determined by factors such as the spot size of a laser beam, the laser power density, the gas pressure of the thin gas, the type of the thin gas and the like.
The laser beam is continuous laser or pulse laser; the wavelength is in the ultraviolet to infrared range, preferably the visible range.
The laser propelling distance of the graphene material in the rarefied gas can reach more than meter level, the propelling distance is not limited in principle, and the attenuation of the graphene material only comes from weak loss of laser energy during transmission in the rarefied gas.
The graphene material disclosed by the invention has no loss or damage in the laser propulsion process, and can realize continuous light propulsion without supplementing any fuel.
The graphene material can also be used as a carrier of other objects to realize laser propulsion in a dilute gas, such as embedding other materials (such as metal powder) in graphene, or connecting graphene and other materials (such as magnesium aluminum alloy), but the other materials are not limited to the listed materials, and other materials or objects not listed are also applicable.
Compared with the prior art, the method overcomes the defect that the block material is difficult to effectively push due to small light radiation pressure in the prior art, adopts a laser radiation method to directly push the graphene material in the rarefied gas by the laser beam, can also directly push other materials by taking the graphene as a carrier, can realize non-contact pushing of the graphene or other related objects without any fuel, has the driving force far greater than the light pressure (radiation pressure), and has the advantages of simplicity, high efficiency, environmental protection and wide application prospect.

Fig. 5 is a photograph of graphene in a static state when the air pressure is 2Pa in example 1 of the present invention.
The specific implementation mode is as follows:
in order to better explain the present invention and to facilitate understanding of the technical solutions, the present invention is further described in detail by the following embodiments in conjunction with the accompanying drawings.
Example 1:
the specific process of graphene laser propulsion in a rarefied gas in the embodiment includes:
(1) as shown in fig. 2, a graphene material 4 is suspended on a support 6 by a suspension wire 5 according to a classical pendulum model in physics, and the graphene material 4, the suspension wire 5 and the support 6 are put into a transparent closed container 3 filled with air, wherein fig. 3 is a physical photograph of the experimental device;
(2) using an air pump to pump air into the transparent closed container 3, and reducing the air pressure to 8Pa to create a thin air environment;
(3) as shown in fig. 4, the laser beam emitted by the laser irradiates the graphene material in the rarefied air from right to left, the spot diameter of the used laser beam is about 2mm, the power is 50mW, the wavelength is 488nm, and the graphene material 4 continuously swings under the laser irradiation, so that the obvious laser propulsion is realized; fig. 4 is a photograph of graphene swinging to the highest point, and it should be noted that in the device, when graphene swings to the highest point, the illumination cross section is the smallest, and the laser pushing force applied to the graphene is the weakest, so that the graphene returns to the lowest point under the action of gravity, and in fact, if the laser beam pushes the graphene to move in the horizontal direction, the graphene continuously moves along the illumination direction.
Example 2:
in this embodiment, the air pressure in the transparent closed container is reduced to 2Pa by using an air pump, the other parameter settings are the same as those in embodiment 1, at this time, the graphene irradiated by the laser beam does not swing, a still photograph thereof is shown in fig. 5, and this embodiment illustrates that when the air pressure is too low, the driving force of the laser beam on the graphene is small.
As can be seen from embodiments 1 and 2, the graphene laser propulsion technology in the rarefied gas shown in the present embodiment realizes macroscopic rapid movement in the rarefied gas by irradiating the graphene material in the rarefied gas at a specific gas pressure with a laser beam, and has an obvious effect; the method is simple, efficient, green and environment-friendly, and has wide application prospects in the technical field of propulsion.
