The crystal axis is c. The Main ray is parallel to the way accustomed to measure the tuning angle (θ), that's optimized throughout phase matching. Conversion efficiency is optimized for rays parallel to your chief ray and worse for rays at larger sized angles (ψ) on the Main ray.
β-BBO Crystal—a broadly applied nonlinear crystal for frequency conversion while in the ultraviolet, obvious and near-infrared
Good day, thanks for getting in touch with Thorlabs. The wavelength ranges on 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 often made by achieving out to us at [email protected]
This efficiency is important, especially when a single considers the generation in the 266nm wavelength, the place even minimal inefficiencies can cause considerable Electricity losses.
Last of all, the wide-angle tunability of BBOs facilitates customization like by no means ahead of. Depending on the distinct needs of an application, the crystal is often altered with precision, making certain which the output is usually optimized.
They even have a large injury threshold, enabling them to take care of large-ability laser beams without having degradation. These unique properties make BBO crystals a versatile Device in a variety of optical programs.
Bodily, when the fundamental spectrum is well inside the reference pulse spectrum, the SHG pulse intensity profile is the square of the fundamental depth profile, efficiently truncating the period. This situation is illustrated in Figure 20.
As illustrated in the subsequent table, the shorter the crystal, the wider the reference pulse spectrum. The desk under assumes a essential Middle wavelength within the close to-IR.
In summation, while several crystals give precise strengths within the realm of photonics, BBO crystals emerge as complete powerhouses. They encapsulate A variety of functions that are not just beneficial in isolation but work synergistically, creating a holistic solution for frequency doubling and harmonics era.
Moreover, spectroscopy, a technique that’s basic in analyzing and understanding the Homes of varied substances, reaps the rewards of BBO’s abilities. Spectroscopy relies around the interaction amongst gentle and make any difference to derive insights a couple of material’s composition, composition, and also other Qualities.
Thorlabs offers a large choice of optics optimized to be used with a-BBO Crystal femtosecond and picosecond laser pulses. Please see down below for more information.
When comparing an LIDT specified for any pulsed laser towards your laser, it is essential to know the subsequent:
The next harmonic mild is then polarized parallel to the plane. Angle tuning adjusts θ and it is done by rotating the crystal around the Y-axis.
This information dives deep into the advantages and distinctive properties of BBO crystal and its paramount importance in effective frequency doubling and harmonics technology at 266nm.
