These raw components are carefully measured and blended in precise proportions to ensure the best composition on the resulting crystals.
BBO crystals are grown utilizing the flux system, a procedure that requires melting Uncooked materials at large temperatures. The molten content is then slowly cooled to form a crystal. This process needs specific control of temperature and cooling fee to ensure the crystal’s good quality and integrity.
Thorlabs provides a big choice of optics optimized to be used with femtosecond and picosecond laser pulses. Please see below To find out more.
Note that even if the nominal depth is below the nominal destruction threshold, there may be challenges due to fluctuations inside the beam electricity or regional intensity (e.g., if a beam profile has “scorching spots�?, or because of isolated defects in the crystal, which might be extra sensitive compared to the normal crystal content.
For beams using a significant PRF both the average and peak powers have to be in comparison to the equivalent CW power. Additionally, for extremely transparent resources, There's minimal to no fall during the LIDT with growing PRF.
A common system for obtaining ultrathin crystals is always to initially optically Speak to a thicker nonlinear crystal with a few substrate (e.g. of fused silica) after which you can to polish the crystal down to the demanded thickness of e.
Filters below or the form at the bottom can be employed to aid product or service research or make even more inquiries.
g. twenty μm. The team velocity mismatch while in the thicker substrate materials might not subject, because the nonlinear interaction can take area only in The skinny crystal. The substrate only serves to mechanically stabilize the thin nonlinear crystal.
Working with our promoting package deal, you'll be able to Show your brand, further more underneath your solution description, and these will been observed by several photonics industry experts.
Taken collectively, these assorted purposes underscore the enormous worth BBO crystals carry to many sectors. Through its unparalleled 266nm technology, the BBO crystal is not simply a Instrument but a catalyst, propelling enhancements across distinctive fields.
As Beforehand mentioned, pulsed lasers ordinarily induce a special kind of harm to your optic than CW lasers. Pulsed lasers normally don't warmth the optic ample to wreck it; instead, pulsed lasers generate strong electric fields capable of inducing dielectric breakdown in the material.
Also, it may be really appealing to work with a crystal content which can be critically section-matched at room temperature since noncritical stage matching typically will involve the Procedure of your crystal in a temperature-stabilized crystal oven. Even so, the feasibility of crucial period matching could possibly be presented only more info for adequately significant peak powers.
This can be the so-known as oo-e arrangement, as the two photons from the basic are polarization-oriented together the ordinary axis and the next harmonic photon's polarization is in the extraordinary plane.
Our crystals are used in a variety of programs, together with a variety of forms of nonlinear frequency conversion and electro-optics, but additionally quantum technology.
