In addition to their use in laser frequency conversion, BBO crystals have found purposes in electro-optic modulation and quantum optics experiments.
A next problem would be that the group velocity mismatch involving the next harmonic and basic-frequency pulses will lead to a single pulse lagging one other as The 2 propagate. This is known as temporal wander-off and will happen even under best section-matched situations.
The period matching angle may be altered by rotating the crystal within the y axis. An adjustment that is usually inside of a handful of levels can both optimize the general performance in the crystal inside the setup or match A further fundamental frequency from the crystal's running selection.
The stage-matching capabilities of BBO crystals ought to have Particular point out. Inside the intricate dance of photons, in which conversion from one particular wavelength to another is commonly desired, the phase-matching supplied by BBO makes certain that Electrical power losses are negligible.
Be sure to Notice that We've got a buffer constructed between the required problems thresholds on the web and the tests which We've accomplished, which accommodates variation between batches. Upon ask for, we can offer personal check data and also a tests certificate.
Though the above mentioned procedure supplies a fantastic guideline for LIDT values, be sure to Get hold of Tech Assist In case your wavelength is different from the specified LIDT wavelength. In case your power density is fewer than the altered LIDT of your optic, then website the optic must function to your software.
The angular content of the targeted beam could be visualized by tracing rays through the lens towards the focal place. Every single ray drawn from the lens to some tightly centered place (Figure 23) will make a unique angle (ψ) Along with the chief ray, and the choice of angles raises Along with the NA. Since the number of angles boosts further than the reference NA filter (or angular area apodization filter width), the section-matching of the rays outside of the filter width diminishes for that reason cutting down the SHG conversion efficiency of These rays.
But BBO crystals stand resilient, guaranteeing that units keep on to function without having hiccups, reducing downtimes and guaranteeing Price tag-success Ultimately.
Consequently, the second harmonic pulse spectrum, demonstrated on the appropriate, incorporates a spectral width approximately similar to The best circumstance. Preferably, each and every frequency in the basic pulse spectrum could well be at the same time period matched.
Just about every facet of BBO, from its atomic framework to its wide software spectrum, underscores its pivotal purpose in modern science and engineering.
Certainly, BBO crystals could be personalized In accordance with particular requirements. This contains customized sizes, designs, and coatings. Nonetheless, customization might have an affect on the crystal’s properties and effectiveness, so it should be carried out by knowledgeable. Custom dimensions and designs could be Slash from a larger BBO crystal to suit precise apps.
The 266nm generation refers back to the manufacture of ultraviolet light using a wavelength of 266 nanometers.
