1. Thermal stability: Acousto-optic crystal has good thermal stability, that is, its performance can remain relatively stable within a certain temperature range. This is because the physical and electrical characteristics of acousto-optic crystals are relatively insensitive to temperature changes. Thermal stability is very important for the practical application of acousto-optic devices, which can ensure the reliability and performance consistency of devices under various environmental conditions.
2. Thermo-optic modulation characteristics: Acousto-optic effect means that the existence of sound waves will cause the refractive index of light waves in acousto-optic crystals to change, thus realizing the modulation of optical signals. Acousto-optic modulation is an important optical modulation technology, which is widely used in communication systems and optical fiber transmission. The special temperature characteristics of acoustooptic crystal will affect the effect and stability of acoustooptic modulation. Acousto-optic crystal is a kind of material with special properties, which can convert energy between sound wave and light wave. It is made of some specific crystal or glass materials and has piezoelectric effect and optical effect.
