Beta-Barium borate (or β-BaB2O4, β-BBO) crystal is one of the most eminent nonlinear optical crystals. BBO crystal manifest outstanding optical features such as its high nonlinear optical coefficient, low group velocity dispersion, broad transparency range of 189-3500 nm (The transparency curve are shown in the Resource sector) and high damage threshold. The crystal has an effective frequency doubling coefficient 3-6 times larger than the current general ADP and KDP crystals in the near-infrared, visible and ultraviolet band. It also has a light damage threshold (15Gw/cm2) twice higher than that of KDP , and high optical homogeneity.
These characteristics made beta BBO crystals become a versatile material for various nonlinear optical applications such as harmonic generation operations and optical parametric oscillators(OPO) and optical parametric amplifiers(OPA) and other applications in the field of quantum optics( quantum entanglement) and EO applications. Besides, BBO crystals also excel in low thermal-optical coefficients and availability of large size high quality single crystals.
Hangzhou Shalom EO offers off-the-shelf and customized BBO crystals for nonlinear optical applications. The ultra-thin 0.01mm thickness with fused silica substrates and 0.05mm thickness free standing BBO crystals are available for femto-line lasers. We provide BBO crystals for the usages of :
They are the most effective crystal for 5HG at 213nm and superior for intracavity frequency doubling high power Nd:YAG lasers / THG and FHG Ti:Sapphire lasers / type I SHG and THG of an Alexandrite laser with high energy conversion efficiencies.
Utilizing optical parametric oscillation(OPO) and parametric optical amplification (OPA) of BBO crystal, optcial parametric generation (OPG) one could easily generate a coherent radiation with broad tuning wavelength range (from the UV to IR). Shalom EO provide ultra-thin BBO crystals for femtosecond laser with high phase-velocity and group-velocity matching.
The BBO provided by Shalom EO have extensive usage in the Dye lasers. According to researches,
with type I sum-frequency of 780 - 950 nm and 248.5 nm (SHG output of 495 nm dye laser) in BBO, the shortest UV outputs ranging from 188.9nm to 197 nm and the pulse energy of 95 mJ at 193 nm and 8 mJ at 189 nm have been obtained, respectively.
BBO crytsals have high prospect in the the field of quantum optics and are suitable for electro-optic modulations.

1. Applications in harmonic generations
BBO is an efficient NLO crystal for second harmonic generation(SHG), third harmonic generation(THG), fourth harmonic generation(4HG) and fifth harmonic generation(5Hg). And BBO is the only NLO material which can be used to produce the fifth harmonic generation (5HG) of Nd:YAG lasers at 213 nm. Because of a small acceptance angle and large angular walkoff, good laser beam quality (small divergence, good mode condition, etc.) is the crucial factor for BBO to obtain high conversion efficiency. Tight focus of laser beam is not recommended by Shalom EO's engineer. The phase matching of both type I and type II BBO can be reached by angle tuning. The transparency rate and the tuning curves of second harmonic generation(SHG) are shown in Fig.1 and Fig.2 separately below:
Fig.1 Transparency curve of BBO Fig.2 Tuning curves of type 1 and type 2 BBO
2.The OPO and OPA of BBO crystal
The OPO and OPA of BBO are convenient means to produce a widely tunable coherent radiation from the UV to IR. The tuning angles of type I and type II BBO OPO and OPA at 532nm, 355nm and 266nm are collected and illustrated in Fig. 3 and Fig. 4, respectively.
