Description
Items Notes：
- Size, mm: The first lists the dimensions of the crystal in millimeters; W*H*L(mm)
- θ, deg: The second represents the phase-matching angle θ in degrees. This is the angle at which phase matching occurs for nonlinear optical processes.
- φ, deg: The third represents the azimuthal angle φ in degrees. This angle specifies the orientation of the crystal axis in the plane perpendicular to the propagation direction.
- Coating: The fourth describes the coating applied to the crystal, specifying the wavelength range for which the coating is optimized (e.g., P/P @ 400-800 nm).
Description: Lithium Iodate (LiIO₃) is a nonlinear optical crystal widely used in various applications due to its high transparency range, significant nonlinear coefficients, and excellent phase matching capabilities. It is extensively employed in laser technology, frequency conversion, and electro-optic applications.
