All About BBO crystal - What You Need to Know

BBO (Beta Barium Borate) crystals are nonlinear optical crystals with unique properties that make them valuable in various applications.

What are BBO crystal?

BBO crystals are nonlinear optical crystals composed of beta barium borate (β-BaB2O4). They are often used in various nonlinear optics applications, such as frequency doubling, sum and difference frequency generation, optical parametric oscillation, and more. BBO crystals exhibit a high damage threshold, broad transparency range, and excellent nonlinear optical properties.

Types of BBO crystal

1. Type I are phase-matching cut for a fundamental laser wavelength. They allow for efficient frequency doubling, and their birefringence properties make them suitable for various nonlinear optical processes.
2. Type II are phase-matching cut for a second harmonic generation (SHG) process, where the generated signal is perpendicular to the incident beam. Type II BBO crystals are used in applications where phase matching for SHG is required.
3. Type I are phase-matching cut for a fundamental laser wavelength. They allow for efficient frequency doubling, and their birefringence properties make them suitable for various nonlinear optical processes.
4. Type II are phase-matching cut for a second harmonic generation (SHG) process, where the generated signal is perpendicular to the incident beam. Type II BBO crystals are used in applications where phase matching for SHG is required.
