Applications
Applications of BBO Crystals in the field of Nonlinear Crystals:
BBO for Second, Third, Fourth, and Fifth Harmonic Generation of Nd: YAG Lasers : Exceptional conversion efficiencies could be achieved using BBO crystals, which are greater than 70% (SHG), 60% for THG, 50% for 4thHG. BBO crystal is the best option for 213nm 5HG.BBO crystals excel in the ability to handle intracavity SHG of Nd:YAG lasers with high power densities to generate 532nm output. And 266nm output with a decent power level could be attained using a Brewster-angle-cut BBO crystal when pumping the Nd:YAG Laser with an SHG output of a mode-locked Nd:YLF laser. Because of a small acceptance angle and large angular walk off, good laser beam quality (small divergence, good mode condition, etc.) is the crucial factor for BBO to function better, tight focusing of laser beams is not recommended.
Femtosecond Lasers: For SHG and THG of Femtosecond Lasers, BBO also exhibits a great advantage over KDP and ADP crystals.
Dye Lasers：BBO crystal is an effective media for SHG of XeCl-laser pumped Dye lasers for giving output in the ultra-violet spectrum (205-310nm).
SHG/THG of Alexandrite Lasers and SHG/THG/FHG of Ti:Sapphire Lasers ：SHG/THG of Alexandrite Lasers UV output in the region 360nm-390 nm and output in the region 244nm - 259 nm. SHG/THG/FHG of Ti:Sapphire Lasers could also be realized efficiently.
Intracavity SHG of Argon Doped Lasers and SHG of Copper-Vapor Lasers：Intracavity SHG of Argon Doped Lasers for UV and Deep-UV output, and SHG of Copper-Vapor Lasers for UV output.
Optical Parametric Oscillation (OPO) / Optical Parametric Amplification (OPA): Utilizing BBO crystals for optical parametric oscillation(OPO) and parametric optical amplification (OPA), one could easily obtain tunable output in a broad wavelength range (from the UV to IR). Common applications include: （1）OPO of 532nm pumped lasers for output ranging from 680 nm to 2400 nm and （2）OPO and OPA of 355nm Nd:YAG pumped lasers

Frequently Asked Questions
Chinese brand Barium borate (BaB2O4) was discovered and developed by Chen Chuangtian and others of the Fujian Institute of Research on the Structure of Matter (Fujian CASTECH Crystals), Chinese Academy of Sciences in1980. Barium borate (BaB2O4) is a type of borate mineral that can crystallize in two different forms: alpha-Barium borate (α-BBO) and beta-Barium borate (β-BBO): α-Barium borate (α-BBO): This is a lower temperature phase that can be stable up to 925 degrees Celsius.α-Barium borate, α-BaB2O4, is an excellent birefringent crystal material with a very wide optical transmission window. With good mechanical properties, it is a suitable material for high power UV polarized optics. It is commonly used in Glan-Taylor prisms, Glan-Thompson prisms, Wollaston Polarizers, Spatial Compensators and Time Delay Compensators. β-Barium borate (β-BBO or simply BBO): This is the high-temperature phase and can be stable at temperatures above 925 degrees Celsius. The β-BBO has exceptional nonlinear optical properties With Wide transmission from 190nm to 3500nm and Broad phase-matching range from 409.6nm to 3500nm and is widely used in many areas of physics and engineering.The β-BBO is the form that is typically referred to when discussing "BBO crystals" in the context of optics and laser technology.
BBO (Beta Barium Borate) crystals are nonlinear optical crystals used primarily for frequency conversion, such as second harmonic generation (SHG). They work by exploiting nonlinear optical properties, allowing a high-intensity laser beam to interact with the crystal to produce light at different frequencies. BBO crystals are known for their broad phase matching capabilities, high damage threshold, and large nonlinear coefficient, making them popular in various laser applications.

Once you have identified the BBO crystal tuning axis, the next step is Aligning a BBO (Beta Barium Borate) crystal for optimal nonlinear frequency conversion (e.g., Second Harmonic Generation) requires precise adjustments to ensure maximum conversion efficiency. Secure the BBO crystal in an adjustable mount that allows for angular rotation (typically around both horizontal and vertical axes). and Ensure your laser source is stable. Direct the fundamental beam (the beam you want to convert) through the center of the BBO crystal. It should be perpendicular to the entrance and exit faces. Slowly rotate the BBO crystal around the beam direction. This is the main "tuning" action. While rotating, monitor the converted beam's intensity. For SHG, this would be the second harmonic generation. As you notice the appearance of the second harmonic or the desired converted wavelength, fine-tune the angle to maximize its intensity. The position at which the intensity is highest is your optimal phase matching condition. Tilt the crystal slightly in the vertical plane to check if this enhances the output. This adjustment ensures that the tuning axis is truly optimized in all dimensions. Once you've achieved the maximum output intensity, lock the crystal mount to maintain this position.
