Description

Technical Field

[0001] This utility model relates to the field of crystal observation technology, and in particular to an observation device for the growth state of crystals. Background Technology

[0002] Potassium tantalate niobate (KTN) crystal is the optical crystal with the largest electro-optic (EO) effect among existing materials: high-speed optical control can be achieved by utilizing the electro-optic (EO) effect. KTN crystal is a high-performance, multifunctional nonlinear optical crystal with significant electro-optic and photorefractive effects, as well as good thermal, chemical, and mechanical stability. Based on these advantages, KTN crystal has wide applications in nonlinear optics and laser technology, such as high-speed optical shutters, Q-switches, optical intensity modulators, optical phase modulators, beam deflectors, laser mode-locking, as well as optical storage, optical communication, and optoelectronics.

[0003] KTN (potassium tantalate niobate) crystals are generally grown from tantalate niobate melts using the molten salt method. This method utilizes the miscibility of tantalate niobate and flux at high temperatures, and crystals are prepared by controlling the temperature and concentration. Currently, crystal observation is usually done by workers directly through an observation window, typically located on the side of the crystal growth furnace cavity. However, the distance between the observation window and the crystal growth site is relatively far, making it difficult to observe subtle changes on the crystal surface. This hinders timely adjustments to the growth furnace, thus affecting crystal quality. Utility Model Content
