These raw components are meticulously calculated and combined in exact proportions to ensure the exceptional composition on the resulting crystals.
Whilst the above treatment delivers a great guideline for LIDT values, please Get in touch with Tech Guidance When your wavelength is different from the specified LIDT wavelength. When your electricity density is lower than the altered LIDT of the optic, then the optic ought to work for your personal application.
These Homes make BBO crystals extremely fascinating in a variety of apps, from laser frequency conversion to electro-optic modulation. Their broad transparency array enables them to operate that has a broad choice of laser wavelengths, while their large damage threshold makes certain they will manage superior-electricity laser beams with no degradation.
BBO crystal stays by far the most versatile nonlinear optical crystals due to its special combination of optical Attributes (
BBO is of certain relevance within the visible and much UV. Lots of section-matching programs are achievable, such as the pursuing:
A common process for acquiring ultrathin crystals is always to initially optically Speak to a thicker nonlinear crystal with some substrate (e.g. of fused silica) then to polish the crystal all the way down to the needed thickness of e.
Nevertheless, it’s important to Take note that although BBO crystals can handle significant ability, they should even now be utilised in just their specified electricity selection to circumvent potential destruction and assure exceptional effectiveness.
Most of our conventional crystals come mounted into open ring holders. Make sure you Be aware the letter "H" while in the item code which indicates that crystal is provided mounted.
This calculation assumes a uniform beam depth profile. It's essential to now regulate this Strength density to account for hotspots or other nonuniform intensity profiles and approximately determine a maximum Strength density. For reference a Gaussian beam usually has a greatest energy density that is two times that of the 1/e2 beam.
BBO crystals may be procured from a number of suppliers throughout the world. When choosing a supplier, it’s crucial to consider elements such as the standard of the crystals, the provider’s popularity, and the level of customer care delivered.
The effectiveness with the SHG method decreases significantly as the elemental beam diverges from its concentration, For the reason that pulse Power is dispersed throughout a larger beam cross area.
Exactly what are BBO Crystals? BBO crystals are a sort of nonlinear optical crystal recognized for their vast transparency assortment, high damage threshold, and superb thermal and chemical security.
As a result, the 2nd harmonic pulse spectrum, proven on the appropriate, contains a spectral width somewhere around BBO Crystal the same as The perfect case. Preferably, just about every frequency in the basic pulse spectrum will be concurrently phase matched.
The 266nm wavelength gives unique interactions that other wavelengths can’t, which makes it indispensable for detecting and researching selected compounds.
