BBO Crystal Fundamentals Explained

This informative article dives deep into the advantages and distinctive Qualities of BBO crystal and its paramount relevance in successful frequency doubling and harmonics generation at 266nm.

While the above technique presents a superb guideline for LIDT values, make sure you contact Tech Support In case your wavelength is different from the desired LIDT wavelength. If the ability density is a lot less than the altered LIDT from the optic, then the optic should function for your application. 

Both of those have a relatively reduced problems threshold, but don't must be operated at substantial intensities due to their high nonlinearity. They may have a bent for photorefractive outcomes, that are detrimental for frequency conversion, but are employed for, e.g., holographic data storage in Fe-doped LiNbO3 crystals. The inclination for “photorefractive damage�?relies upon strongly on the material composition; e.g. it might be decreased through MgO doping and through the use of a stoichiometric composition.

It can be extensively useful for nonlinear frequency conversion inside the ultraviolet, visible, and in the vicinity of-infrared. The BBO crystal could be the most critical nonlinear crystal for in close proximity to-infrared optical parametric chirped-pulse amplifiers, which at present produce several optical cycle pulses with significant ordinary and ultrahigh peak powers.

The 2nd harmonic gentle is then polarized parallel towards the airplane. Angle tuning adjusts θ and is also executed by rotating the crystal round the Y-axis.

If the crystal surfaces are still “soiled�?right after the above cleaning methods, the surfaces may need been broken. Be sure to contact us for rework with the crystals.

Temperature degree sensitivity: BBO crystals temperature sensitivity has an effect on their refractive indices and in addition stage-matching difficulties. This desires temperature amount stabilizing or tuning tools to maintain optimum efficiency.

A second problem is that the group velocity mismatch between the 2nd harmonic and fundamental-frequency pulses will end in just one pulse lagging one other as the two propagate. This is known as temporal stroll-off and can take place even beneath optimum stage-matched problems.

Physically, when the fundamental spectrum is very well throughout the reference pulse spectrum, the SHG pulse intensity profile would be the sq. of the fundamental intensity profile, efficiently truncating the duration. This case is illustrated in Figure twenty.

BBO crystals may be acquired from a variety of suppliers around the world. When picking a provider, it’s imperative that you take into account variables like the quality of the crystals, the provider’s status, and the extent of customer support supplied.

Irrespective of whether it’s in the development of much more effective lasers, the exploration of quantum phenomena, or maybe the creation of recent optical products, BBO crystals will unquestionably keep on to Engage in a pivotal position.

They even have a large hurt threshold, letting them to manage superior-electric power laser beams devoid of degradation. These unique Attributes make BBO crystals a flexible Device in a variety of optical applications.

The 266nm technology refers back to the production of ultraviolet gentle having a wavelength of 266 nanometers.

When choosing a supplier, take into account variables such as the supplier’s knowledge, product or service quality, customer service, and pricing. It’s also a smart website idea to request a sample or even a examination report back to validate the caliber of the crystals prior to making a invest in.
