A: Indeed, BBO crystals show remarkable thermal stability, producing them appropriate for applications with various temperatures.
Good day, thanks for calling Thorlabs. The wavelength ranges with the antireflective coatings on these β-BBO crystals align With all the respective wavelength bands that these crystals are optimized for. Requests for customizations is usually made by reaching out to us at techsupport@thorlabs.com
5 mm to attenuate team velocity mismatch and are perfect for frequency doubling or tripling of Ti:sapphire and Yb:doped laser pulses. The important and noncritical period matching LBO crystals are ideal for second or 3rd harmonic era of Nd:YAG and Yb:doped lasers.
Now Review the maximum energy density to that which happens to be specified given that the LIDT for that optic. If the optic was analyzed in a wavelength apart from your functioning wavelength, the harm threshold need to be scaled correctly [3].
BBO crystals could be cleaned using a comfortable fabric or air blower. For stubborn stains, a mild detergent or isopropyl alcohol can be used. It’s important to prevent making use of abrasive elements that could scratch the crystal’s floor. When cleaning BBO crystals, it’s imperative that you use a delicate, round movement to stop scratching the surface.
A typical approach for obtaining ultrathin crystals should be to 1st optically contact a thicker nonlinear crystal with a few substrate (e.g. of fused silica) then to polish the crystal down to the essential thickness of e.
Figure 18: The common and amazing refractive indices of β-BBO differ with frequency and wavelength resulting from a fabric house referred to as dispersion. Dispersion exists in all media besides vacuum.
Presented these apps, it’s obvious why BBO, with its inherent capacity to competently deliver the 266nm wavelength, is so remarkably prized. The crystal’s exclusive nonlinear optical Qualities help the conversion of other wavelengths in the coveted 266nm light, making certain that scientists and industries have access to this critical Software.
Beam diameter is likewise crucial to know when evaluating hurt thresholds. Though the LIDT, when expressed in units of J/cm², scales independently of spot measurement; significant beam sizes usually tend to illuminate a larger quantity of defects which can cause better variances while in the LIDT [four].
Taken together, these various programs underscore the immense benefit BBO crystals website provide to many sectors. By its unparalleled 266nm technology, the BBO crystal is not merely a Instrument but a catalyst, propelling advancements throughout distinct fields.
NCPM occurs once the enter beam propagates at an angle besides zero or 90 levels worrying among the major axes, including the Z-axis. Its polarization is parallel to that axis, including Z-polarized.
In addition, BBO crystals are known for their substantial nonlinear coefficient, which permits them to effectively change the frequency of light.
Any contamination can degrade the optical effectiveness of your crystal and possibly result in hurt less than superior laser energy. When storing BBO crystals, they need to be put in a protective case to stop physical harm and dust accumulation.
Some makers' SHG crystals, such as Thorlabs', deliver in close proximity to-phase-matched disorders for Commonly incident input gentle to get a specified essential frequency. These companies polish the faces of your SHG crystals this sort of which the angle among the Ordinarily incident mild as well as optic axis may be the section-matched angle for the desired frequency.
