A1: Yes, BBO crystals Possess a substantial problems threshold, making them ideal for large-energy laser techniques. Their capability to withstand high laser intensities without having suffering from optical damage will make them a fantastic choice for frequency conversion in substantial-power lasers.
The position in the green curve will depend on θ. In such a case, the angle θ continues to be tuned to offer a refractive index for 515 nm gentle that matches the refractive index for 1030 nm light. This tuning angle is for that reason optimized for Style-I SHG section matching along with a basic-frequency enter beam of 1030 nm.
When one of these β-BBO Crystals is mounted within the RSP1 mount, the crystal will probably be centered about the eight-32 (M4) gap inside the mount's base without the want for spacers.
Determine 23: This diagram illustrates a beam's focal area inside a uniaxial birefringent substance. Straight lines, symbolizing rays, are drawn with the Centre in the beam waistline. Because the beam diverges within the beam waistline, the energy inside the beam is dispersed around a larger cross sectional place.
Make sure you Be aware that We now have a buffer developed between the desired damage thresholds on the web and the checks which We have now completed, which accommodates variation in between batches. Upon request, we can offer unique take a look at facts in addition to a screening certificate.
Bodily, when the basic spectrum is nicely throughout the reference pulse spectrum, the SHG pulse intensity profile could be the square of the elemental intensity more info profile, effectively truncating the length. This case is illustrated in Determine 20.
The destruction Evaluation will be carried out on an analogous optic (shopper's optic will not be destroyed). Screening may possibly bring about added prices or guide periods. Make contact with Tech Support To learn more.
Now Evaluate the maximum Strength density to that that's specified since the LIDT to the optic. In the event the optic was examined at a wavelength apart from your functioning wavelength, the injury threshold should be scaled correctly [three].
The SHG light-weight is polarized within the XZ plane and is particularly orthogonal to each the Eo as well as k-vector. In lieu of decompose the polarization on the SHG light into Ex and Ez elements, the electric discipline is usually described as a rare wave (E'e). The refractive index for this remarkable wave, n'e, alterations like a perform of θ. n'e(θ) can be calculated using the equation in Figure 13. The ellipse defining the extraordinary index of refraction as being a functionality of θ is a conic area on the index ellipsoid.
BBO crystals, with their distinctive Houses and wide selection of applications, are getting to be a cornerstone in the sphere of optics and photonics. These crystals, known for their large transparency variety, large hurt threshold, and excellent non-linear optical Houses, have revolutionized the way in which we manipulate mild, opening up new possibilities in various scientific and technological fields.
Beta Barium Borate (BBO) crystals have taken the earth of photonics by storm. Just about the most spectacular components of these crystals is their revolutionary job in 266nm era.
The Actual physical, chemical, optical, and thermal Qualities of the α -BBO are much like those on the BBO crystals, however the α -BBO would not exhibit the nonlinear optical Houses because of the central symmetry of its crystal framework.
In addition, the structural and compositional attributes of BBO offer it with outstanding thermal stability and resistance against environmental worries.
