Optical parametric oscillation (OPO): We employ OPO to ascertain our merchandise�?nonlinear conversion functionality and section-matching angle for the presented input wavelength and signal/idler wavelengths. We make selected that our objects meet the necessities for OPO applications.
EKSMA Optics makes use of cookies to supply you with the best browsing practical experience. In the event you keep on to implement our providers, we will presume that you simply comply with using these kinds of cookies.
The 266nm technology ensures that these interactions are finely tuned, permitting researchers to glean insights with Improved precision. Whether or not it’s in researching complex molecules, deciding the Qualities of recent resources, or in environmental monitoring, the BBO crystal’s capability to create 266nm light amplifies the depth and precision of spectroscopic scientific studies.
Be aware that whether or not the nominal depth is below the nominal problems threshold, there may be troubles as a consequence of fluctuations in the beam power or regional intensity (e.g., if a beam profile has “incredibly hot places�?, or as a consequence of isolated defects inside of a crystal, which might be far more sensitive in comparison to the common crystal product.
, the angle in between the light's propagation course and also the crystal's optic axis is usually tuned so that the refractive index of a particular frequency (ω) in the fundamental input pulse specifically equals the refractive index of 2 times the input frequency (twoω). It truly is normal to improve phase matching problems for that frequency at somewhere around the center of the heart beat's bandwidth.
Remember to find your delivery state to see by far the most precise stock info, and to determine the right Edmund Optics gross sales office for the purchase.
Now Review the maximum electricity density to that that is specified because the LIDT to the optic. If your optic was analyzed in a wavelength other than your working wavelength, the hurt threshold have to be scaled properly.
A 2nd problem is that the team velocity mismatch amongst the second harmonic and essential-frequency pulses will cause just one pulse lagging the other as the two propagate. This is called temporal wander-off and can occur even under exceptional stage-matched problems.
A: A higher injury threshold ensures the crystal can manage extra energy without having degrading, leading to lengthier lifespan and regular overall performance.
For CPM, we Reduce our pieces at an angle equivalent to no or 90 degrees worrying one of several significant axes. For NCPM, we lessened our things at an angle determined by Snell’s regulation:
Pumped through the fourth harmonic of a Nd:YAG laser (at 266nm), a tunable OPO with signal wavelength vary involving 422nm more info and 477nm has actually been observed by angle-tuning a sort I BBO crystal. Pumped by a 1mJ, 80fs Dye laser at 615nm, the OPA with two BBO crystals yields much more than 50µJ (highest 130µJ),
There aren't any objects as part of your cart. Insert objects to the cart and request an official quote or buy on the net Subtotal
And lastly, spectroscopy, the research of interactions among make any difference and electromagnetic radiation, drastically Positive aspects through the 266nm technology. In spectroscopic applications, various wavelengths of light interact in different ways with products, supplying a spectrum that may be analyzed to find out the fabric’s Attributes or composition.
When selecting a supplier, look at elements like the supplier’s practical experience, merchandise quality, customer service, and pricing. It’s also a good idea to request a sample or perhaps a take a look at report back to validate the standard of the crystals before making a buy.
