BBO, is a nonlinear optical crystal that is widely used in various fields such as telecommunications, medical equipment, and scientific research. BBO crystals have a high damage threshold, wide transparency range, and excellent nonlinear optical properties, making them ideal for frequency conversion applications. BBO crystals are highly resistant to photorefractive damage and have a low sensitivity to temperature changes. These properties make BBO crystals a popular choice for high-power laser systems, nonlinear frequency conversion, and quantum optics experiments.
