You should consider the wavelength and energy within your laser resource and decide on a crystal which is clear at the offered wavelength and might stand up to the laser electricity. Last of all, other elements including the thermal steadiness, optical homogeneity, and nonlinear optical coefficient of the crystal also have to be viewed as.
Hygroscopic crystal materials deteriorate when they're not generally retained in adequately dry air (or a dry purge gas). This is applicable e.g. to KDP and BBO, As well as in a lesser extent to LBO. It could be handy to keep this type of crystal in a to some degree elevated temperature, which makes it simpler to continue to keep it dry.
XRD can even be utilised to determine the crystal high quality and defects inside the crystal, such as twinning and dislocations.
Dennis is an engineer with about forty five a long time of experience in fabrication, testing, and product evaluation for prime precision optics, with substantial arms-on knowledge. More about the writer are available below.
A standard process for acquiring ultrathin crystals is always to 1st optically Get in touch with a thicker nonlinear crystal with a few substrate (e.g. of fused silica) after which you can to shine the crystal all the way down to the demanded thickness of e.
The Czochralski system is often a very well-established technique for expanding significant, high-quality one crystals. It includes melting the starting supplies in a crucible and bit by bit pulling a seed crystal from your melt while rotating the crystal to take care of uniform progress.
No matter if it’s a small-temperature scientific experiment or simply a high-temperature industrial procedure, you'll be able to rely on LBO Crystals to deliver consistent functionality. Their ability to keep up their nonlinear optical Qualities throughout a broad temperature vary additional augments here their flexibility.
Dust and stains on crystal surfaces might cause scattering/loss of light and may even react with mild to damage optical surfaces in a higher incident laser power.
LBO Crystals have cemented their position being an integral Portion of the laser market, contributing appreciably to progress in laser technology. Having a high destruction threshold and great optical homogeneity, LBO Crystals can stand up to the substantial-intensity outputs which have been commonplace in superior-electric power laser techniques, successfully enabling these units to complete optimally without having hazard of damage to their parts.
If you don't locate the suited products earlier mentioned, you may let's know your requirements or applications in the form underneath. Our profits or technological staff members can get back again for you at the earliest opportunity.
Many different Qualities of the nonlinear crystal is usually significant for an application e.g. in nonlinear frequency conversion:
Sum-frequency era (SFG) is actually a nonlinear procedure that involves the conversion of two enter photons into one output photon that has a frequency equivalent for the sum from the input frequencies. LBO nonlinear crystals Use a higher nonlinear coefficient, which makes them perfect for economical SFG.
The understanding of these strategies is critical for the design and optimization of crystal progress processes along with the creation of large-good quality LBO nonlinear crystals for a variety of programs in optics and photonics.
