The higher injury threshold of BBO crystals is particularly vital in environments where by high-intensity lasers are classified as the norm. Common supplies could possibly falter, degrade, or perhaps split beneath these types of intensities.
The duration of the SHG crystal substantially impacts the spectral width in the reference pulse, or alternatively the bandwidth in the SHG filter.
Hi there, thank you for making contact with Thorlabs. The wavelength ranges of your 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 produced by achieving out to us at techsupport@thorlabs.com
The phase matching angle is usually altered by rotating the crystal within the y axis. An adjustment that is typically inside of a number of levels can possibly improve the efficiency with the crystal in the set up or match A different fundamental frequency from the crystal's functioning vary.
Any contamination can degrade the optical performance in the crystal and most likely induce destruction below significant laser electrical power. When storing BBO crystals, they should be positioned inside a protective case to forestall physical destruction and dust accumulation.
Provided these apps, it’s obvious why BBO, with its inherent capability to effectively produce the 266nm wavelength, is so highly prized. The crystal’s one of a kind nonlinear optical Qualities enable the conversion of other wavelengths in the coveted 266nm light-weight, making sure that scientists and industries have access to this vital Software.
Whilst the above mentioned treatment provides a very good general guideline for LIDT values, please contact Tech Aid When your wavelength differs from the specified LIDT wavelength. Should your ability density is fewer than the altered LIDT of your optic, then the optic should really work to your software.
The physical, chemical, optical, and thermal Homes of the α -BBO are much like All those of the BBO crystals, however the α -BBO won't exhibit the nonlinear optical Attributes because of the central symmetry of its crystal composition.
Now compare the most Electrical power density to that and that is specified because the LIDT for the optic. In case the optic was examined at a wavelength besides your working website wavelength, the injury threshold have to be scaled correctly [3].
Consequently, the 2nd harmonic pulse spectrum, proven on the proper, provides a spectral width around the same as The perfect scenario. Preferably, each and every frequency in the elemental pulse spectrum could be at the same time stage matched.
The fundamental supply is the dye laser radiation pumped by the second harmonic of the Q-switched Nd: YAG laser. A stroll-off compensated configuration Along with the BBO crystal pair has enabled us to realize this kind of significant conversion efficiency during the conversation.
This is the so-referred to as oo-e arrangement, as the two photons from the fundamental are polarization-oriented along the standard axis and the second harmonic photon's polarization is inside the extraordinary airplane.
The Bodily, chemical, optical, and thermal Qualities in the α -BBO are similar to All those with the BBO crystals, though the α -BBO doesn't show the nonlinear optical Attributes as a result of central symmetry of its crystal structure.
This article dives deep into the advantages and distinctive Houses of BBO crystal and its paramount importance in effective frequency doubling and harmonics era at 266nm.
