It connects, the other side is connect with absorber 18.Its through-hole and incident light are coaxial, and through-hole structure according to the angle of divergence δ of incident light at loudspeaker
Mouth diffusion type.And the wall surface S of through hole4And the face S towards absorber 183Mirror surface treatment is done, reflects layman as reflecting surface
Light beam.It is the side being connect with absorber 18 towards the face of absorber 18.17 interior design of antireflection diaphragm has cooling water channel,
For cooling down its reflecting surface S3And S4。
The entirety of conical reflector 19 is in cone structure, and it is reflecting surface that front, which is the conical surface towards laser light incident hole 37,.The conical surface
The conical reflecting face S of reflecting mirror 191, absorber 18 cylindrical inner wall absorbing surface S2And antireflection diaphragm 17 is towards absorber 18
Face S3And the wall surface S at intermediate throughholes4, it forms a cylindrical front and back and reflects, the absorption inner cavity of intermediate absorption energy,
Incident laser shakes reflection-absorption back and forth in it.
Since the taper angle theta that the essential condition that incident laser forms back concussion reflection-absorption is exactly conical reflector 19 compares laser
Big 90 ° of angle of divergence δ or more.Meanwhile under the same terms, the taper angle theta of conical reflector 19 is smaller, and incident laser is in absorber 18
Cylindrical inner wall absorbing surface S2On length direction single shake back and forth absorption when, can order of reflection it is more, i.e. energy absorption number is got over
It is more, speed is faster.And the conical reflecting face S of conical reflector 191Concave structure i.e. in concave circular arc shape relative to linear
Shape, the edge light beam of incident laser, in the conical reflecting face S of conical reflector 191On when only reflecting one time, conical reflector 19
Taper angle theta it is smaller, i.e. when the taper angle theta of conical reflector 19 is identical, the interior concave circular arc shape of conical reflector 19 is relative to straight line
Shape, the central light beam of incident laser when single on 18 length direction of absorber shakes absorption back and forth, can order of reflection it is more.
In addition, the interior concave circular arc shape of conical reflector 19 can also be such that the first time of the edge light beam of incident laser absorbs
Point and the first time of central light beam absorb point, in the cylindrical inner wall absorbing surface S of absorber 182What is be distributed on length direction is longer,
That is the two spacing distance is bigger, so that the Energy distribution for making the first time of total light beam absorb point is more uniform, simultaneously because laser
The Gaussian Profile of light beam, edge amount of beam is smaller relative to the energy density of central light beam, first time of edge light beam absorb point from
Antireflection diaphragm 17 can also receive the case where being closer.
Using the conical reflecting face S of reasonable conical reflector 191Interior concave circular arc shape, cooperate reasonable conscope cone angle
θ can reach during once shaking reflection-absorption back and forth, the conical reflecting face S of conical reflector 191With antireflection diaphragm 17
Reflecting surface face S3、S4Only reflection is primary, and the absorbing surface S of absorber 182Upper reflection-absorption number as much as possible, and
The purpose of first time energy absorption distribution more evenly, to reach higher energy absorption efficiency.
On the basis of the above embodiments, further, laser absorption component further includes shell 20.Shell 20 is in first end
