The Greatest Guide To BBO Crystal
Blog Article
A: Yes, BBO crystals exhibit impressive thermal stability, generating them ideal for apps with different temperatures.
While the above process presents a good general guideline for LIDT values, you should Get in touch with Tech Guidance In the event your wavelength differs from the desired LIDT wavelength. If the electricity density is below the altered LIDT of your optic, then the optic must operate to your software.
We reduced our boule into smaller sized merchandise In keeping with client specs employing a ruby blade, or twine noticed machine. After that, polish these items making use of ruby powder or slurry on Solid iron or copper plates.
) is The crucial element for BBO to get superior conversion performance. Limited aim of laser beam is just not suggested.
Second harmonic era (SHG): We use SHG to measure our objects�?nonlinear conversion efficiency and stage-matching angle for just a specified enter wavelength. We assurance that our things fulfil the necessities for SHG purposes.
EKSMA Optics uses cookies to provide you with the very best browsing knowledge. For those who keep on to make use of our products and services, we will presume you comply with using this sort of cookies.
The cutting angle relies upon on the preferred period-matching problem for frequency conversion purposes. Phase matching describes matching the period speeds of various beams connected with nonlinear procedures so that they Make up constructively above fars absent In the crystal.
Beta Barium Borate (BBO) crystals have taken the earth of photonics by storm. Probably the most amazing components of these crystals is their revolutionary function in 266nm era.
A5: Yes, BBO crystals have superb thermal balance and can preserve their Qualities at area temperature. Consequently they may be used in a wide array of environments devoid of requiring Specific temperature Regulate.
In practice, γ is nonzero once the polarization states of sunshine inside a laboratory reference body are not matched on the intrinsic principal axes during the crystal body. To orient the two reference frames alongside one another, e.g. the vertically polarized light-weight with the laser on the optical desk is parallel to inside the crystal, we mount the nonlinear crystal in the rotation phase to finely modify γ to zero, initial by eye using the markings about the housing and then more, if necessary, utilizing the SHG output electrical power as responses.
At such a selected wavelength, the light possesses unique properties that are invaluable to certain advanced purposes. Enable’s delve further into the value of this specific light-weight output.
Pulsed lasers with large pulse repetition frequencies (PRF) might behave in the same click here way to CW beams. Sadly, this is extremely depending on factors including absorption and thermal diffusivity, so there is not any dependable strategy for analyzing any time a higher PRF laser will hurt an optic as a consequence of thermal consequences.
Thus, the second harmonic pulse spectrum, demonstrated on the best, has a spectral width about the same as The best situation. Preferably, every single frequency in the elemental pulse spectrum can be simultaneously stage matched.
The 266nm wavelength delivers unique interactions that other wavelengths can’t, rendering it indispensable for detecting and learning particular compounds.
