β-Barium borate (β-BaB2O4 or BBO) is a nonlinear optical crystal which has been widely used in non-linear optical applications like OPO, OPA, OPCPA and other. Due to its large spectral transmission range as well as phase matching, BBO crystals have been applied in second, third, fourth or fifth harmonic generations for high power visible/UV sources and optical parametric conversions for high power broadly tunable sources. Since its broad gain bandwidth overlaps with Ti:Sapphire in 800 nm range, ultra-high power and high contrast laser systems have been built based on the mixed CPA/OPCPA plan.

β-Barium borate (β-BaB2O4 or BBO) is a nonlinear optical crystal which has been widely used in non-linear optical applications like SHG, THG, OPO, OPA, OPCPA and other.

In summary, AR coating enhances your lenses’ durability, reduces glare, and makes cleaning easier. It also enhances your glasses’ appearance and, most importantly, your comfort. When shopping for eyeglasses, consider selecting AR-coated lenses. If you find prices high at physical stores, reputable online retailers like Zenni Optical offer excellent value, with standard AR coatings starting at just $4.95. Properly maintained AR-coated glasses promise a superior eyewear experience.

AR coating plays a crucial role in eliminating glare from both the front and back surfaces of your lenses. Here’s why it matters:
