LBO Crystals and Components

Lithium Triborate (LiB3O5 or LBO) is an excellent nonlinear crystal with wide transparency range, relative large effective nonlinear coefficient, high damage threshold and good chemical and mechanical properties. LBO allows temperature-controlled Non-Critical Phase-Matching (NCPM) for 1.0-1.3 μm, Type I SHG, and also provides room temperature NCPM for Type II SHG at 0.8-1.1 μm. It also possesses a relatively large angular acceptance bandwidth, reducing the beam quality requirements for pump lasers.

LBO crystal (Lithium triborate) is a non-linear optical material of choice for frequency converting high power lasers with its following main features:
>High bulk damage threshold
>Small walk-off angle
>Non-critically phase-matched SHG possible at a large range of near-infrared wavelengths
>High transparency in the UV, making it the best option for THG 355nm or THG 343nm
>Possibility of sum-frequency generation of DUV wavelengths

ULTI Crystal can provide large aperture LBO crystals which can be used for harmonic generation and OPO of high average/peak power Q-switched Neodymium lasers, where other crystals can't withstand. Non-critical phase matching in wide range achievable by temperature tuning allows to employ long crystals without any walk-off influence on nonlinear interaction efficiency. Especially this application is attractive for CW and quasi-CW lasers.

What makes us different:
>Ultra-low bulk absorption : <2ppm/cm@1064nm
>Outstanding polishing and coating quality, enabling a 300W UV-laser
>Long lifetime under UV-exposure: 10.000+ hours at 30W on one single spot
>Coating damage thresholds >40J/cm²@1064nm, 10ns for dual-AR coating
>Available size up to 100x100mm²; length up to 100mm

	Notes
	»| LBO has a very low susceptibility to moisture. Users are advised to provide dry conditions for both the use and preservation of LBO.
	»| Polished surfaces of LBO requires precautions to prevent any damage.
	»| 149 °C temperature is required to achieve Non-Critical Phase Matching (NCPM) in LBO at type 1 SHG of 1064 nm application.
	»| For thin LBO crystal, ULTICRYSTAL can provide free holder for you.
	»| The custom sizes is available upon requested
