Custom coatings is often placed on the crystal surfaces to boost their overall performance at particular wavelengths or to shield the crystal from environmental things. Nevertheless, it’s vital that you Observe that any customization must be done very carefully to stop degrading the crystal’s optical Homes.
The difficulty that arises when working with ultrashort pulses for next harmonic generation (SHG) is the fact shorter pulses have greater bandwidths, but The best stage-matched affliction could be obtained For under one fundamental wavelength at any given time. As a result of this, the quality of the stage match may be considerably even worse in the direction of the spectral edges of broad-bandwidth pulses.
The 266nm generation ensures that these interactions are finely tuned, letting scientists to glean insights with Improved precision. No matter if it’s in studying elaborate molecules, analyzing the Qualities of recent supplies, or in environmental monitoring, the BBO crystal’s power to generate 266nm gentle amplifies the depth and accuracy of spectroscopic scientific studies.
) is The real key for BBO to obtain superior conversion performance. Limited concentrate of laser beam is just not proposed.
Ordinarily, the crystal material must have a large optical transparency for all wavelengths included �?by way of example, for pump, sign and idler in an optical parametric amplifier.
EKSMA Optics works by using cookies to provde the best shopping check here practical experience. In case you continue to make use of our solutions, We're going to suppose which you conform to using these kinds of cookies.
Now compare the utmost electric power density to that that's specified because the LIDT with the optic. When the optic was tested in a wavelength besides your functioning wavelength, the damage threshold has to be scaled properly.
Supplied these apps, it’s obvious why BBO, with its inherent ability to proficiently create the 266nm wavelength, is so extremely prized. The crystal’s exceptional nonlinear optical properties allow the conversion of other wavelengths in the coveted 266nm light, making sure that researchers and industries have use of this vital Software.
The high problems threshold of BBO crystals is particularly significant in environments wherever substantial-intensity lasers are definitely the norm. Standard components could possibly falter, degrade, as well as break less than these intensities.
To circumvent this, BBO crystals need to be saved within a dry setting and correctly sealed when not in use. On top of that, any cleansing procedure should be accompanied by thorough drying to eliminate any residual dampness.
When comparing an LIDT specified for your pulsed laser for your laser, it is vital to understand the next:
rystal surface is horizontal and somewhat previously mentioned your fingers. Take a refreshing, clear sheet of lens tissue and location it within the crystal. Be sure the lens tissue might be drawn over the crystal surface area. Subsequent, location a little fall of pure isopropyl Liquor (IPA) around the lens tissue on top of the crystal area.
Any contamination can degrade the optical overall performance on the crystal and likely cause injury beneath significant laser power. When storing BBO crystals, they need to be positioned in a very protecting circumstance to prevent physical damage and dust accumulation.
Optical parametric amplification (OPA): We use OPA to evaluate our items�?nonlinear conversion effectiveness and stage-matching angle for just a provided input wavelength and sign/idler wavelengths. We guarantee that our products meet the specs for OPA applications.
