This short article dives deep into the advantages and exclusive Houses of BBO crystal and its paramount value in economical frequency doubling and harmonics technology at 266nm.

g. in the shape of “gray tracking�? These kinds of phenomena are notably frequent for operation with ultraviolet light. Notice that a gradual degradation might also direct into immediate catastrophic harm through excessive warmth generation.

The damage analysis is going to be performed on an analogous optic (consumer's optic won't be broken). Tests may perhaps result in supplemental expenses or lead instances. Get hold of Tech Assistance for more information.

BBO crystal continues to be the most flexible nonlinear optical crystals as a result of its special mixture of optical Qualities (

Hygroscopic crystal resources deteriorate when they are not constantly stored in sufficiently dry air (or maybe a dry purge gasoline). This applies e.g. to KDP and BBO, and in a lesser extent to LBO. It can be beneficial to help keep this type of crystal at a rather elevated temperature, that makes it easier to preserve it dry.

The team velocity would be the speed of the heart beat, or more formally the envelope of the electrical field. The team index similarly governs the speed of your envelope relative towards the pace of sunshine inside a vacuum and is dependent on the dispersion of the fabric.

β-BBO Crystal—a widely used nonlinear crystal for frequency conversion from the ultraviolet, obvious and in the vicinity of-infrared

This distinctive mixture makes sure that β-BBO crystal can be a promising applicant for nonlinear optical applications including frequency converters and optical parametric oscillators. In quantum optics, β-BBO crystal can produce entangled photon pairs and 10-photon entanglement.

This calculation assumes a uniform beam depth profile. You have to now modify this Electricity density to account for hotspots or other nonuniform intensity profiles and around estimate a most Electricity density. For reference a Gaussian beam usually features a highest Power density that is 2 times that on the one/e2 beam.

The period matching angle might be modified by rotating the crystal within the y axis. An adjustment that is often inside of a few levels can possibly optimize the general more info performance of the crystal inside the setup or match One more fundamental frequency in the crystal's operating vary.

Pumped by the fourth harmonic of a Nd:YAG laser (at 266nm), a tunable OPO with sign wavelength range in between 422nm and 477nm has long been noticed by angle-tuning a kind I BBO crystal. Pumped by a 1mJ, 80fs Dye laser at 615nm, the OPA with two BBO crystals yields in excess of 50µJ (highest 130µJ),

On the other hand, in lots of scenarios, the primary difference in the elemental and next harmonic pulse velocities can result in a person pulse to noticeably lag one other.

And finally, spectroscopy, the examine of interactions amongst make a difference and electromagnetic radiation, significantly Advantages in the 266nm generation. In spectroscopic apps, unique wavelengths of light interact differently with supplies, offering a spectrum that may be analyzed to ascertain the fabric’s Homes or composition.

This decreases the productive communication measurement and likewise lowers the conversion efficiency. Such as, BBO crystals have an angular stroll-off of about 38 mrad for SHG at 1064 nm wavelength, which has to try and do with six times larger than KDP crystals.
