The selection with the most fitted crystal product for the provided software is commonly far from trivial; it should involve the thought of numerous facets. By way of example, a high nonlinearity for frequency conversion of ultrashort pulses would not enable Should the conversation length is strongly constrained by a significant group velocity mismatch as well as minimal damage threshold limits the relevant optical intensities.
If the Rayleigh assortment is below the crystal thickness, the gap in excess of which the beam is optimally powerful is less than the crystal thickness.
Now Evaluate the most Electrical power density to that which is specified as being the LIDT for your optic. In the event the optic was analyzed at a wavelength other than your functioning wavelength, the injury threshold must be scaled properly [3].
BBO is of certain value within the seen and far UV. Numerous types of stage-matching apps are possible, including the pursuing:
Superior damage threshold: BBO crystals have large damage limits that can stand up to their substantial best and usual power without the need of degradation or damage.
Nevertheless, it’s imperative that you Be aware that whilst BBO crystals can deal with substantial ability, they need to even now be made use of inside of their specified electrical power selection to forestall opportunity destruction and make certain best general performance.
Beta Barium Borate (BBO) crystals are a topic of curiosity in the sphere of optics and photonics because of their special Attributes. In this article, we goal to answer ten typical questions on BBO crystals, furnishing an extensive comprehension of this fascinating materials.
For buyer convenience the crystals is usually mounted within an 1" anodized aluminum (Al) mount. The mounted crystals can be further mounted in a traditional one" here mirror mount to get angle tuned for section matching (as demonstrated to the appropriate). Water-cooled mounts for high electric power apps might be provided upon ask for.
Rather than decompose the SHG polarization into factors Ex and Ez, The sunshine is typically referred to as a rare wave (E'e) with a refractive index, n'e. During the diagram on the appropriate, n'e, which relies on θ, is indicated with the intersection in the conic section illustrated via the purple ellipse With all the XZ airplane.
Whether or not it’s in the event of much more successful lasers, the exploration of quantum phenomena, or even the creation of latest optical devices, BBO crystals will certainly continue to Enjoy a pivotal function.
In frequency conversion, BBO crystals are accustomed to change the shade of laser gentle, enabling the creation of a wide array of hues that aren't straight accessible from obtainable laser sources. In electro-optic modulation, They can be utilised to regulate the intensity, phase, polarization, or course of the laser beam.
In combination with their large hurt threshold, BBO crystals also show fantastic thermal and chemical stability. They are able to stand up to a wide array of temperatures and resist degradation from several chemical interactions.
Optical parametric amplification (OPA): We use OPA to evaluate our parts�?nonlinear conversion performance and phase-matching angle for a delivered enter wavelength and sign/idler wavelengths. We promise that our merchandise meet up with the specs for OPA apps.
