Description
The LBO Crystal, or Lithium Triborate (LiB3O5), is a highly esteemed nonlinear optical crystal known for its exceptional properties. With a wide transparency range spanning from 210 nm to 2300 nm, LBO crystals are versatile and suitable for a variety of optical applications. Their moderately nonlinear coupling and high damage threshold make them a preferred choice in environments where durability and performance are crucial.
One of the standout characteristics of LBO crystals is their ability to achieve non-critical phase matching (NCFM) conditions for Type I Second Harmonic Generation (SHG) at wavelengths between 1000 nm and 1300 nm. This feature allows LBO crystals to be free from walk-off limitations, enabling the use of longer crystals for enhanced performance. Additionally, LBO crystals are free from the gray track effect, making them particularly valuable in high-power green laser applications.
Beyond their optical properties, LBO crystals boast excellent chemical and mechanical stability, ensuring longevity and reliability in various operational settings. Their precise dimensional tolerances and superior wavefront distortion characteristics further enhance their appeal, providing users with a high degree of accuracy and consistency. The combination of these attributes makes LBO crystals an indispensable component in advanced optical systems.
