Embodiment Construction

[0017] figure 2 Be the optical path diagram of the multifunctional beam inverter of the present invention, as figure 2 As shown, the multifunctional beam inverter of the present invention includes reflector I 201, reflector II 202, lens III 203, electro-optic switch 204, reflector III 205, reflector IV 206, reflector V 207, lens IV 208, reflector VI 209 and reflector Ⅶ210; the laser beam emitted by the laser enters the lens Ⅲ203 through the mirror Ⅰ201 and the mirror Ⅱ202 and is converted into parallel light, so that the large-diameter beam in the main amplifier is converted into a medium-diameter beam, which is convenient for transmission in the multi-functional beam inverter; parallel The beam passes through the electro-optical switch 204 which conducts the main laser pulse and isolates the self-excited oscillation and anti-laser, and then enters the 90° corner body composed of the mirror III 205, the mirror IV 206 and the emission mirror V 207; the 90° corner body is para...

Abstract

The invention provides a multifunctional light beam reverser. According to the multifunctional light beam reverser, a laser beam emitted out by a laser enters a lens III through a reflector I and a reflector II and is converted into parallel light, and a large-diameter light beam in a main magnifier is converted into a medium-diameter light beam so that the light beam can be conveniently transmitted in the multifunctional light beam reverser; parallel beams enter a 90-degree angle turning body formed by a reflector III, a reflector IV and an emitting lens V after passing through an electro-optical switch which is conductive to main laser pulses and isolative to self-oscillation and anti-lasers; the 90-degree angle turning body carries out 90-degree rotation on a near field and the polarization state of the parallel beams; the parallel beams are converged through a lens IV, and then are guided out through a reflector IV and a reflector VII. When the multifunctional light beam reverser is adopted, the energy output characteristic of a system is improved; astigmatism is converted into out-of-focus, and the far-field quality of output light beams of the system can be obviously improved further through lens focusing compensation.

Description

technical field [0001] The invention belongs to the technical field of high-power lasers, and in particular relates to a multifunctional beam inverter used in a multi-pass laser amplification system. Background technique [0002] At present, many countries in the world are building high-power laser devices for inertial confinement fusion (ICF) research, and have adopted the overall technical route of "square beam + multi-pass amplification". "Square beam" refers to changing the laser device from the previous single-beam design to a multi-beam array design in order to further improve the xenon lamp pumping efficiency of the chip amplifier, thereby improving the energy storage efficiency of the system. The corresponding unit components or modules (such as spatial filtering devices, electro-optical switches, etc.) mostly adopt combined structure; at the same time, adopting combined structure design can reduce the volume of the system and help to reduce the installation space; i...
