Crystal

Simplified Introduction to Optical Crystals​
Optical crystals are key components in optical systems. They control light’s movement and features via effects like refraction, polarization, and more.​
Main Types​
1.Laser Crystals (e.g., Nd:YAG, YVO₄): Turn energy into laser light for lasers;​
2.Nonlinear Optical Crystals (e.g., KTP, BBO): Change laser wavelengths to expand uses;​
3.Polarization Crystals (e.g., Iceland spar, quartz): Create or adjust polarized light for imaging and communication;​
4.Electro-optical/Acousto-optical Crystals (e.g., LN, TeO₂): Control light’s strength and phase for switches and modulators.​
Key Uses​
With high uniformity, low loss, and stability, they’re widely used in laser devices, optical communication, medical imaging (CT, endoscopes), industrial testing, and semiconductor lithography—critical for precise light control in high-end optical products.
