This text dives deep into the benefits and special Houses of BBO crystal and its paramount value in successful frequency doubling and harmonics era at 266nm.
EKSMA Optics takes advantage of cookies to provide you with the very best browsing encounter. For those who keep on to work with our companies, we will assume you agree to the usage of these cookies.
And lastly, the huge-angle tunability of BBOs facilitates customization like hardly ever ahead of. Depending on the specific needs of the software, the crystal could be modified with precision, ensuring that the output is often optimized.
Note that regardless of whether the nominal intensity is underneath the nominal harm threshold, there might be challenges resulting from fluctuations in the beam ability or nearby depth (e.g., if a beam profile has “very hot spots�?, or on account of isolated defects in a crystal, which are additional delicate when compared to the frequent crystal material.
Instead of the reference pulse electrical power spectrum comprising an apodization filter, during the spatial domain the filter could well be in NA. The angular domain apodization filter having said that, is barely in one-dimension described because of the aircraft k and .
BBO crystals have two refractive indices: ne for remarkable rays and no for usual rays. The distinction between ne and no will depend on the wavelength of light as well as the crystal’s temperature.
There's two velocities that outline the propagation of sunshine in optical media: the section click here and team velocities. The period velocity may be the pace with the provider, the oscillation of the electric industry, as well as velocity that's matched amongst the basic and 2nd harmonic frequencies for section matching. The stage velocity relative to your pace of sunshine in the vacuum is described because of the index of refraction.
Nonlinear Crystals of both β-barium borate (BBO) or lithium triborate (LBO) are useful for frequency conversion of laser sources. BBO crystals element thicknesses from 0.2mm to 0.5mm to minimize team velocity mismatch and are perfect for frequency doubling or tripling of Ti:Sapphire and Yb:doped laser pulses. The vital and noncritical phase matching LBO crystals are perfect for 2nd or 3rd harmonic technology of Nd:YAG and Yb:doped lasers.
Making use of our promotion deal, you are able to Exhibit your emblem, additional beneath your product or service description, and these will been found by quite a few photonics experts.
A: The broad transparency selection features flexibility, allowing BBO crystals for use throughout a diverse selection of wavelengths and apps.
BBO crystals are renowned for their Fantastic optical Houses. Their extensive transparency selection permits them to operate correctly throughout a broad spectrum, from ultraviolet to in the vicinity of-infrared mild. This can make them extremely functional and suitable for several different programs.
Also, it can be hugely desirable to use a crystal substance that may be critically stage-matched at room temperature for the reason that noncritical stage matching normally will involve the operation on the crystal in a very temperature-stabilized crystal oven. Having said that, the feasibility of significant phase matching might be offered just for adequately significant peak powers.
Third harmonic era (THG): We use THG to evaluate our items�?nonlinear conversion usefulness and stage-matching angle for just a offered enter wavelength. We Make certain that our products and solutions satisfy the specs for THG applications.
When selecting a provider, consider elements such as the supplier’s encounter, item good quality, customer support, and pricing. It’s also a smart idea to request a sample or a exam report back to validate the caliber of the crystals before you make a purchase.
