Problems solved by technology
The crystal heat sink under the influence of vibration will cause the position of the heat sink to hold the crystal to change, which will affect the relevant optical properties of the crystal (such as coupling efficiency, thermal field distribution, mode matching, etc.), and then affect the beam pointing and optical power of the entire system. And important parameters such as beam quality, serious changes may even cause the system to fail to operate normally

The invention relates to a crystal vibration reduction and heat sink device which comprises a heat sink element and further comprises at least one vibration sensor, a feedback control element and at least one dynamic vibration absorber. The vibration sensor is used for sensing the vibration frequency of the heat sink element. The feedback control element is used for controlling each dynamic vibration absorber to generate equivalent mass according to the vibration frequency, so that the ratio of the vibration frequency of the heat sink element to the inherent frequency of the dynamic vibration absorber meets the optimal homology condition, and the damp of the dynamic vibration absorber meets the optimal damp condition. Each dynamic vibration absorber generates equivalent mass to absorb the vibration of the heat sink element. By the adoption of the technical scheme, the dynamic vibration absorber can well absorb the vibration generated by the heat sink element when the heat sink element is influenced by different vibration sources.
Description
technical field [0001] The invention relates to the technical field of crystal temperature control and vibration reduction, in particular to a crystal vibration reduction heat sink device. Background technique [0002] The crystal heat sink is an important part of the solid optical system, which mainly solves the problems of crystal clamping and cooling. The influence of vibration in the actual application environment on the crystal heat sink is an important aspect that cannot be ignored in the design of the crystal heat sink. Crystal heat sinks are affected by vibration mainly from two aspects: 1. Environmental vibration, such as the operation of large-scale instruments around, construction operations, etc.; 2. Vibration of cooling sources, such as water coolers, refrigeration compressors, etc. The crystal heat sink under the influence of vibration will cause the position of the heat sink to hold the crystal to change, which will affect the relevant optical properties of t...
