The superior injury threshold of BBO crystals is especially critical in environments where superior-intensity lasers are definitely the norm. Traditional elements may possibly falter, degrade, as well as split less than this kind of intensities.
However, it can be very difficult to match the LIDT specification of the optic to the laser. There are many regimes through which a pulsed laser can harm an optic which is based over the laser's pulse duration. The highlighted columns during the table below outline the applicable pulse lengths for our specified LIDT values.
While this general guideline delivers a standard pattern, It's not at all a quantitative Examination of LIDT vs wavelength. In CW purposes, As an illustration, problems scales additional strongly with absorption in the coating and substrate, which does not always scale perfectly with wavelength.
The stage matching angle may be modified by rotating the crystal round the y axis. An adjustment that is typically in just a few levels can either enhance the performance with the crystal within the set up or match another fundamental frequency in the crystal's running assortment.
The Power density of the beam ought to be calculated with regards to J/cm2. The graph to the best displays why expressing the LIDT as an Electrical power density offers the top metric for brief pulse resources. Within this regime, the LIDT presented as an Vitality density might be placed on any beam diameter; a person will not ought to compute an modified LIDT to regulate for modifications in spot sizing.
The effectiveness from the SHG course of action decreases considerably as the basic beam diverges from its emphasis, Considering that the pulse Vitality is dispersed across a larger beam cross area.
The realm of fabric processing has equally benefited within the precision of 266nm technology. State-of-the-art microfabrication methods, which entail intricate detailing on resources in a microscopic degree, need an actual gentle supply. The sharpness associated with the 266nm wavelength makes sure that lasers could make precise cuts, etches, and modifications.
The harm Examination will likely be carried out on a similar optic (buyer's optic will not be ruined). Testing may perhaps end in added expenses or guide periods. Speak to Tech Assistance For more info.
This house sets it besides linear optical supplies that don’t alter the frequency of sunshine passing through them. This kind of distinguishing feature forms the muse for just a myriad of applications that BBO can provide.
For that reason, the second harmonic pulse spectrum, revealed on the correct, has a spectral width about the same as The perfect situation. Preferably, each frequency in the fundamental pulse spectrum might be concurrently section matched.
Filters beneath or the shape at The underside may be used to help solution search or make further more inquiries.
Since the dynamics of this method are remarkably matter to experimental parameters, it really is hard to arbitrarily forecast the exact effects on the 2nd harmonic pulse. These outcomes can include things like back again conversion, during which next harmonic gentle is transformed back to click here essential light, and spectral narrowing from the SHG pulse.
Thermal fluctuations are a priority in many experimental and industrial setups. However, BBO crystals�?intrinsic thermal balance ensures that they don’t just endure but thrive in these types of disorders.
Finally, spectroscopy, the review of interactions among issue and electromagnetic radiation, drastically Rewards from your 266nm generation. In spectroscopic programs, distinctive wavelengths of light interact in different ways with elements, furnishing a spectrum that could be analyzed to determine the material’s Qualities or composition.
