Bonded Crystals
Flatness: <λ/10@632.8nm; surface quality: 10/5; parallelism: <10 arc seconds; perpendicularity: <5 arc minutes; bevel: 0.1mm@45°; coating: AR or HR; optical quality, interference fringes: ≤0.125/inch. Bonded crystals join a laser crystal to one or two pure, undoped pieces of the same host material using bonding technology. Experiments show reduced crystal temperature and reduced thermal-lensing effects from end-face deformation.

An infrared transmitter (IR transmitter) is a basic electronic component that sends invisible infrared light signals for short-range wireless control. It is widely used in daily electronics, smart home devices, and industrial equipment due to its low cost, low power consumption, and stable performance.
In photonics and laser technology, devices that manipulate optical signals via the electro-optic effect form the backbone of precision optical systems. Electro-optic phase modulators and electro-optic deflectors are two prominent examples of this device category. As a critical hardware solution for high-speed, high-accuracy laser beam direction control, electro-optic deflectors are widely deployed across industrial and research settings. Below is a detailed overview of their core structure, key performance drivers, and primary use cases.
