This performance is vital, specially when a single considers the technology with the 266nm wavelength, where by even minor inefficiencies can result in considerable Electricity losses.
Hello, thank you for calling Thorlabs. The wavelength ranges on the antireflective coatings on these β-BBO crystals align Together with the respective wavelength bands that these crystals are optimized for. Requests for customizations may be made by achieving out to us at [email protected]
We lessened our boule into lesser things In accordance with shopper requirements employing a ruby blade, or wire saw device. Following that, polish these items using ruby powder or slurry on Forged iron or copper plates.
) is The true secret for BBO to get higher conversion performance. Limited emphasis of laser beam is not really suggested.
Typically, the crystal material should have a significant optical transparency for all wavelengths involved �?such as, for pump, signal and idler within an optical parametric amplifier.
BBO crystals have two refractive indices: ne for remarkable rays and no for standard rays. The distinction between ne and no will depend on the wavelength of sunshine as well as crystal’s temperature.
Their supremacy In this particular domain is not only by accident, but a results of their intrinsic and meticulously crafted properties.
This difference triggers period mismatch in between several mild polarization parts when propagating by way of a BBO crystal. Adjusting the angle amongst the beam and crystal axes can compensate for this phase mismatch.
Bodily, when the fundamental spectrum is nicely throughout the reference pulse spectrum, the SHG pulse intensity profile would be the square of the fundamental depth profile, effectively truncating the duration. This scenario is illustrated in Determine 20.
For the reason that dynamics of this method are really subject to experimental parameters, it is challenging to arbitrarily forecast the exact results on the next harmonic pulse. These consequences can include back again conversion, where next harmonic gentle is converted back again to basic mild, and spectral narrowing in the SHG pulse.
Also, the structural and compositional attributes of BBO give it with amazing thermal security and resistance in opposition to environmental troubles.
Exactly what are BBO Crystals? BBO crystals are a sort of nonlinear optical crystal known for their vast transparency array, significant hurt threshold, and great thermal and chemical security.
3rd harmonic technology (THG): We use THG to evaluate our items�?nonlinear conversion usefulness and phase-matching angle for just a specified enter wavelength. We Be certain that our solutions satisfy the specs for THG applications.
As a result of its excellent Houses BBO crystal incorporates a variety of advantages for various apps, like NOPA with fsec pulses, harmonics era (as much as fifth) of Nd:YAG and Nd:YLF lasers, frequency doubling or tripling website of femtosecond Ti:Sapphire and dye lasers, OPO at Type 1 and kind two stage-matching, E/O switching for Pockels cells and a number of other.
