Abstract

Disclosed is a two-dimensional cross type medium pool for a serial laser combination in Brillouin amplification, which relates to a medium pool. The invention aims to solve the problem that to suffice the laser incident beam and the emission beam at two directions is difficult, and to adjust the fine cross and overlapping of the two laser beams in the medium pool is also difficult in the prior noncollinear structure medium pool of the serial laser combination. The small end part of a first subassembly and the small end part of a second subassembly of the invention are mutually jointed and communicated with each other. A first component (1) and a third component (3) are symmetrically arranged at the upper end face and the lower end face of a second component (2) taking the second componentas the center; and the three components are communicated with each other. A fourth component (4) and a sixth component (6) are symmetrically arranged at the upper end face and the lower end face of afifth component (5) taking the fifth component as the center; and the three components are communicated with each other. The medium pool of the invention makes the laser beam to be perpendicular to the injection window when the laser beam is injected into the medium pool, and fulfils a larger cross angle within the limitation of the permitted errors of the wave vector mismatch angle. The medium pool of the invention also simplifies the structure and realizes the cross and overlapping of the laser beam in the medium pool with convenient adjusting.

Description

technical field

[0001] The invention relates to a medium pool. Background technique

[0002] In the bundle structure based on the non-collinear Brillouin amplification structure unit 100 (see Figure 5 ), a seed beam 118 interacts with the pumping beams 106, 109, 114 and 117 successively through the non-collinear Brillouin amplification structure units 100, 101, 102 and 103. In the non-collinear Brillouin amplification structure unit 100, the seed beam 118 and the pumping beam 106 interact in the medium cell 105 at a fixed angle to complete the amplification of the seed beam 118 by the pumping beam 106, and the amplified seed The beam 118 is output by the non-collinear Brillouin amplification structure unit 100, and the remaining pumping beam 106 enters the optical trap 104, and the angle is determined by the light intensity and aperture of the seed beam 118 and the pumping beam 106, and the length of the dielectric pool 105 . With the non-collinear Brillouin amplifying st...
