Abstract

Disclosed is a three-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. A first component and a second component of the invention are inter-crossed; a third component and a fourth component are also inter-crossed; the middle part of the first component, the second component, the third component, the fourth component and the fifth component are all communicated with each other. The medium pool of the invention makes the Strokes beam and the pump beam to be perpendicular to the injection window when the Strokes beam and the pump beam are injected into the medium pool, and fulfils a larger cross angle within the limitation of the permitted errors of the wave vector mismatch angle. A plurality of pump beams can interact with the Strokes beam at the same time in a single serial laser combination structure unit. An adjusting beam passing through the medium pool can realizes the cross and overlapping of the beams in the medium pool.

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 6 ), 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 is output by the non-collinear Brillouin amplification structure unit 100, and the remaining pumping beam 106 enters the optical trap 104. 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 cell 105. With the non-collinear Brillouin amplifying structure un...
