This information dives deep into the benefits and exceptional Attributes of BBO crystal and its paramount great importance in economical frequency doubling and harmonics technology at 266nm.

Up coming, the power/Electricity is both enhanced or diminished plus the optic is exposed at ten new places. This method is repeated right up until injury is noticed. The destruction threshold is then assigned being the best power/energy which the optic can endure without the need of leading to harm. A histogram including that beneath signifies the tests of one BB1-E02 mirror.

Last of all, the extensive-angle tunability of BBOs facilitates customization like hardly ever in advance of. Depending upon the specific needs of an application, the crystal is usually adjusted with precision, guaranteeing the output is often optimized.

As the second harmonic gentle propagates, its Electrical power flows in a special course than that of the fundamental mild.

Ordinarily, the crystal material ought to have a significant optical transparency for all wavelengths concerned �?by way of example, for pump, signal and idler in an optical parametric amplifier.

Their special Qualities make them a most popular option for numerous demanding and superior-precision optical apps.

The majority of the typical nonlinear crystals like BBO, LBO, BiBO or KTP for frequency doubling, tripling and quadrupling of the basic laser radiation can be obtained from inventory. Purchaser-distinct dimensions and AR coatings will also be made available at aggressive selling prices.

Supplied these apps, it’s apparent why BBO, with its inherent functionality to effectively deliver the 266nm wavelength, is so very prized. The crystal’s exclusive more info nonlinear optical Attributes permit the conversion of other wavelengths in to the coveted 266nm light-weight, guaranteeing that researchers and industries have entry to this critical Resource.

The team velocities of the fundamental and 2nd harmonic pulses may also be diverse, even when section-matched, and also the magnitude on the team velocity mismatch will depend on the crystal Attributes and also the optical frequencies within the pulses.

Smaller acceptance angle: BBO crystals have a little acceptance angle that restrictions the input gentle beam’s mild beam divergence and prime method top quality for successful regularity conversion.

The effectiveness of your SHG method decreases significantly as the fundamental beam diverges from its target, Considering that the pulse Electrical power is dispersed throughout a bigger beam cross portion.

BBO nonlinear crystal is really a unfavorable uniaxial crystal. It provides period matching for many second-purchase interactions Nearly around its whole transparency vary. This transparency ranges from 185 nm to 3.3 µm, as inferred from transmittance measurements applying crystal samples of a few mm thickness.
