Lithium Triborate (LBO) crystals are versatile nonlinear optical materials offering unparalleled transparency across the wavelength range of 160–2600 nm. Known for their high optical homogeneity and absence of photorefractive damage, LBO crystals are a leading choice in photonics for SHG, THG, and optical parametric oscillation (OPO). These crystals exhibit a high damage threshold, ensuring stability in high-intensity laser setups.
LBO’s orthorhombic crystal structure and non-critical phase-matching (NCPM) capabilities further enhance its suitability for applications requiring precise wavelength generation and harmonic conversion. Its broad acceptance angle and minimal walk-off make it particularly effective in maintaining beam quality. POC offers LBO crystals fabricated to stringent standards, ensuring reliability and customization options for various industries, including medical imaging, industrial processing, and defense.
