YCOB Crystals

Outstanding Nonlinear Optical Properties: YCOB exhibits a nonlinear optical coefficient equivalent to that of BBO and LBO crystals, making it highly effective for nonlinear optical applications.

Large Aperture and High Damage Threshold: With a sizable aperture and a high damage threshold in the femtosecond regime (approximately 2000-2500 GW/cm2), YCOB is capable of handling high-power laser applications.

Wide Acceptance Angle and Small Dispersion Angle: YCOB’s wide acceptance angle and small dispersion angle make it ideal for precise and efficient laser beam manipulation.

Stable Thermal and Chemical Properties: YCOB boasts stable thermal and chemical properties, with significantly less thermal expansion than LBO, and non-deliquescent characteristics, ensuring long-term reliability in various environments.

Excellent Machining Properties: YCOB crystals are easy to machine, allowing for precise shaping and sizing to meet specific application requirements.

Applications: High-Power Lasers, Parametric Nonlinear Processing, Optical Frequency Multiplication, etc.
