Abstract

The invention provides a regenerative amplification system used for the laser amplification. The amplification system comprises a spot shaping part, a two-way import and export part and a cyclic amplification part which are connected successively. The spot shaping part is used for shaping a near field of a light beam into a desired shape. The two-way import and export part is used for injecting the light beam into the cyclic amplification part, and realizing the separation of the output light beam and input light beam from the cyclic amplification part. The cyclic amplification part is used for transmitting and amplifying the shaped light beam in a shape-preserving mode repeatedly and arbitrarily. The regenerative amplification system has the advantages of realizing the repeated and arbitrary amplification of the shaped light beam in a conformal mode and realizing the high-gain amplification and great power export and applying to a complicated laser device at the same time on the basis of a gain amplifier with a low large caliber, and simplifying a device structure greatly.

Description

technical field [0001] The invention belongs to the technical field of laser amplification devices, and in particular relates to a regenerative amplification system for laser amplification. By adopting the invention, any number of times of shape-conserving amplification can be realized for the shaped light beam, and high-gain amplification and large energy output can be realized at the same time. Background technique [0002] In laser technology, the regenerative amplifier system has been widely used as a technical solution capable of achieving high-gain amplification. However, the regenerative amplifier system is a resonant cavity structure. Due to the limitation of the mode volume, the maximum output energy of the regenerative amplifier system is limited to the order of millijoules. Moreover, due to the mode forming process in this kind of amplification system, the output spot distribution is determined by its own structure, and the injection light cannot be amplified wit...
