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).
