Abstract: Provided is a sequential-pulse single-frequency laser power amplification apparatus, which comprises a sequence control unit for modulating and switching a source laser to output a primary laser, and a power amplification unit for amplifying the primary laser to output a secondary laser. Also provided is a sequence controllable multi-laser system comprising a plurality of single-frequency and/or multi-frequency laser power amplification apparatuses. This allows a single ultra-narrow linewidth laser device to meet the experimental requirements of multiple platforms in an atomic experiment, achieving high performance at low costs.

Abstract: A device for isolating vibrations includes an ion trap, a cryocooler, a primary chamber, a secondary chamber, a vacuum ion pump, a heat exchanger, a sample chamber, a support part, a connector, a heat conduction part, a first platform, a second platform, and a flexible connecting part. The primary chamber, the secondary chamber, and the vacuum ion pump are fixedly disposed on the first platform. The connector is a hollow structure disposed between the primary chamber and the secondary chamber. The primary chamber communicates with the secondary chamber via the hollow structure thereby forming an airtight chamber. The vacuum ion pump is connected to the primary chamber via a five-way flange. The support part is fixed on the second platform. The cryocooler is fixed on the support part. The cryocooler includes a cold head and a machine head. The cold head is suspended in the primary chamber.
