A: Yes, BBO crystals exhibit remarkable thermal security, making them appropriate for programs with various temperatures.
BBO is the one NLO product which may be used to provide the fifth harmonic generation (5HG) of Nd:YAG lasers at 213 nm. As a result of a little acceptance angle and huge angular walkoff, superior laser beam top quality (modest divergence, superior mode issue, etcetera.
This type of ability is a must have in scenarios the place a particular light frequency is necessary, though the source doesn’t The natural way provide it. By making use of BBO’s Qualities, scientists and engineers can efficiently “tune�?their mild resources to ideal frequencies.
Borates including LBO and BBO also do the job properly in broadly tunable optical parametric oscillators and optical parametric chirped-pulse amplification.
The 2nd harmonic mild is then polarized parallel to your plane. Angle tuning adjusts θ and is also carried out by rotating the crystal within the Y-axis.
Their exclusive Attributes make them a most popular option for numerous demanding and significant-precision optical programs.
This publish-up will explain how we crank out substantial-top quality BBO crystals at our business. We can even assessment some rewards and difficulties of employing BBO crystals for regularity conversion.
BBO crystals are an important ingredient in several optical applications due to their exceptional Homes. Understanding their output, Houses, managing, and usage will help buyers enhance their performance and lifespan.
Employing our promotion package, you'll be able to Show your symbol, additional down below your item description, and these will been noticed by lots of photonics professionals.
Any scratches can degrade the optical functionality of the crystal and probably cause problems beneath higher laser electric power. For stubborn stains, an answer of mild detergent or isopropyl Alcoholic beverages can be gently applied to the crystal floor after which you can rinsed off with distilled water.
High nonlinear coefficients: BBO crystals have sizeable nonlinear coefficients which make economical frequency conversion processes with small input BBO Crystal energy calls for attainable.
BBO nonlinear crystal is really a destructive uniaxial crystal. It offers phase matching for many next-get interactions Virtually about its full transparency assortment. This transparency ranges from 185 nm to three.3 µm, as inferred from transmittance measurements employing crystal samples of a few mm thickness.
The wavelength of the light utilised as well as angle at which it enters the crystal may effects the crystal’s overall performance. Correct alignment and managing in the crystal are vital to attaining optimal overall performance.
This decreases the productive interaction size as well as lowers the conversion efficiency. One example is, BBO crystals have an angular walk-off of concerning 38 mrad for SHG at 1064 nm wavelength, which has to do with six occasions greater than KDP crystals.
