Description

A kind of device handling the round Airy beam direction of propagation

Technical field

The utility model relates to a kind of Optical devices, particularly relates to one and can handle the round Airy beam direction of propagation Device.

Background technology

Circle Airy beam refers to that in definition initial light field meetsOne Light beam, wherein Airy () is Airy function, and R is the radius of circle Airy beam, and w is beam radius, and a is circle The guillotine factor of Airy beam.Circle Airy beam is to be found by researcher in 2010 and realize experimentally , due to its distinctive self-focusing characteristic, can converge so that light intensity increases at communication process energy, thus draw Play the extensive concern of science personnel.

The circle special self-focusing property list of Airy beam now in need not by any external condition, from Hot spot the least can be pooled during propagation, and energy comparison is low before focusing, at focusing Light intensity increases rapidly, is also quickly become a some shaped laser spot the least by ring-type hot spot, and this makes circle Airy Light beam has the biggest using value at the aspect such as particle capture and manipulation and obtains the extensive pass of researcher Note.

But, inventor of the present utility model finds: the propagation justifying Airy beam under normal circumstances can only be followed Its original fixing track so that be restricted, such as when particulate manipulates owing to being subject in a lot of application Hinder and obstruction thing cannot be walked around and cause restriction.Manipulation to circle Airy beam also has researcher in theory Research, but the concrete device being actually available to carry out this operation does not the most find.

A kind of device handling the round Airy beam direction of propagation, including first silver bullion and second silver medal Block and electrolyte, described first silver bullion has a first surface；Described second silver bullion has one Two surfaces, described second surface is oppositely arranged with described first surface, and described first surface and second surface Between shape in an angle, described angle is between-90≤θ≤90；Described electrolyte is positioned at described first silver medal Between block and the second silver bullion.

Wherein in a kind of embodiment, described first silver bullion and the second silver bullion are respectively cuboid.

Wherein in a kind of embodiment, described electrolyte is air.

Relative to prior art, the device of round Airy beam that what the utility model embodiment was provided handle leads to Crossing use silver bullion, air, as electrolyte, forms simple structure；This device is used to handle circle Airy beam Propagation time, it is only necessary to by change between two silver bullions formed angle, easy and simple to handle, its for handle circle Chinese mugwort In light beam provide a kind of practicable method, in machining, the field such as biology, medical science, military affairs and The aspect extensive application prospects such as micro-manipulation.

Accompanying drawing explanation

In order to be illustrated more clearly that the technical solution of the utility model, will make required in embodiment below Accompanying drawing be briefly described, it should be apparent that, below describe in accompanying drawing the most of the present utility model Some embodiments, for those of ordinary skill in the art, on the premise of not paying creative work, Other accompanying drawing can also be obtained according to these accompanying drawings.

Fig. 1 is that the structure of the device handling the circle Airy beam direction of propagation that the utility model embodiment provides is shown It is intended to and principle schematic.

Detailed description of the invention

Below in conjunction with the accompanying drawing in the utility model embodiment, to the technical side in the utility model embodiment Case is clearly and completely described, it is clear that described embodiment is only that the utility model part is real Execute example rather than whole embodiments.Based on the embodiment in the utility model, ordinary skill people The every other embodiment that member is obtained under not making creative work premise, broadly falls into the utility model The scope of protection.

As it is shown in figure 1, the utility model embodiment provides a kind of dress handling the round Airy beam direction of propagation Putting 100, described device 100 includes first silver bullion 10 and second silver bullion 30.

Described first silver bullion 10 and the second silver bullion 30 are respectively cuboid in the present embodiment.

Wherein, described first silver bullion 10 has a first surface 10A；Described second silver bullion 30 has one Individual second surface 30A, described second surface 30A are oppositely arranged with described first surface 10A, and described Between one surface 10A and second surface 30A formed an angle theta, described angle theta be positioned at-90≤θ≤90 it Between, and using air as electrolyte 50 between described first silver bullion 10 and the second silver bullion 30.

In the present embodiment, as it is shown in figure 1, the size of described first silver bullion 10 and the second silver bullion 30 is long (z Direction of principal axis) 10 centimetres, wide (x-axis direction) 5 centimetres, high (y-axis direction) 3 centimetres.

Wherein during a kind of use, by controlling the angle between the first silver bullion 10 and the second silver bullion 30 Direction (the z of x, y, z in θ (namely the angle between first surface 10A and second surface 30A) and figure Direction is the direction of propagation of incident light)；By circle Airy beam by electrolyte in this device 100 50 (note into The round Airy beam direction of propagation penetrated is parallel with z-axis)；Then, change wherein according to the direction of required manipulation Angle theta change the linear optics potential field that this device 100 produces, the value of angle theta for-90≤θ≤90, As θ<when 0, circle Airy beam is by deflecting on the right side of z-axis, as θ>0, circle Airy beam will be on the left of z-axis Deflection, during θ=0, circle Airy beam is propagated along the z-axis direction.

Around this principle control the direction of propagation that circle Airy beam is different.Fig. 1 < draws behaviour by θ as a example by 0 Result after Zong.

According to process used above it can be seen that in the present embodiment, the first silver bullion 10 and the second silver bullion 30 The linear optics potential field model handled required for circle Airy beam 200, electrolyte 50 (air) is produced for building The medium can propagated as circle Airy beam 200；Linear optics potential field can be produced by described device 100, Circle Airy beam 200 can be handled by this potential field, and uses this potential field will not destroy round Airy beam The characteristics such as 200 self-focusings self having, self-healing and salt free ligands；It addition, when circle Airy beam 200 is by being somebody's turn to do During device 100, can be by changing the folder between the angle theta between the first silver bullion 10 and the second silver bullion 30 Angle changes produced linear optics potential field, thus handles the direction of propagation of round Airy beam 200.

Relative to prior art, what what the utility model embodiment provided provided handles round Airy beam 200 Device 100 by using first, second silver bullion 10,30, air is as electrolyte 50, and composition is simple Structure；When using the propagation that this device 100 handles circle Airy beam 200, it is only necessary to by changing two silver The angle theta formed between block 10,30, easy and simple to handle, it provides one for handling circle Airy beam 200 Practicable method, in machining, the aspect such as field and micro-manipulation such as biology, medical science, military affairs has Wide application prospect.

Last it is noted that above example is only in order to illustrate the technical solution of the utility model, rather than right It limits；Although the utility model being described in detail with reference to previous embodiment, this area common Technical staff is when understanding: the technical scheme described in foregoing embodiments still can be modified by it, or Person carries out equivalent to wherein portion of techniques feature；And these amendments or replacement, do not make relevant art The essence of scheme departs from the spirit and scope of the utility model each embodiment technical scheme.
