This informative article dives deep into the advantages and special Qualities of BBO crystal and its paramount relevance in successful frequency doubling and harmonics technology at 266nm.
BBO is the only real NLO material that may be made use of to supply the fifth harmonic generation (5HG) of Nd:YAG lasers at 213 nm. As a consequence of a small acceptance angle and huge angular walkoff, good laser beam good quality (modest divergence, great mode situation, and so forth.
If the Rayleigh array is a lot less than the crystal thickness, the space about which the beam is optimally intensive is under the crystal thickness.
The performance of BBO crystals is usually affected by several variables. The caliber of the crystal alone is paramount, as defects or impurities can degrade its optical Homes. The temperature at which the crystal operates could also influence its efficiency, as changes in temperature could potentially cause thermal expansion or contraction, possibly altering the crystal’s optical Attributes.
Large-top quality crystals may have much less defects and produce better general performance, whilst a highly regarded supplier will stand at the rear of their products and present assistance when desired. Excellent customer care also can make the obtaining system smoother and more fulfilling.

β-BBO Crystal—a widely utilized nonlinear crystal for frequency conversion during the ultraviolet, obvious and close to-infrared
BBO crystals are an important element in lots of optical apps because of their Excellent Houses. Being familiar with their output, Qualities, dealing with, and more info use might help customers enhance their general performance and lifespan.
It’s essential to keep away from working with abrasive resources or powerful solvents, as these can scratch or normally hurt the crystal’s area. Regular cleansing may also help keep the crystal’s optical overall performance and prolong its lifespan.
By way of example, anti-reflective coatings can be placed on minimize gentle decline as a result of reflection, though protecting coatings may be used to enhance the crystal’s resistance to environmental factors. Customization allows for optimum general performance in specific applications.
BBO crystals are renowned for his or her Remarkable optical properties. Their vast transparency assortment makes it possible for them to operate efficiently across a wide spectrum, from ultraviolet to near-infrared mild. This tends to make them amazingly adaptable and appropriate for a range of apps.
In frequency conversion, BBO crystals are utilized to alter the coloration of laser light-weight, enabling the production of a wide range of colors that are not immediately available from readily available laser resources. In electro-optic modulation, These are utilised to control the depth, stage, polarization, or direction of a laser beam.
As well as their substantial destruction threshold, BBO crystals also show superb thermal and chemical balance. They could endure a variety of temperatures and resist degradation from numerous chemical interactions.
This decreases the productive interaction size and in addition lowers the conversion performance. For instance, BBO crystals have an angular walk-off of regarding 38 mrad for SHG at 1064 nm wavelength, which has to accomplish with six moments much larger than KDP crystals.
