XRD entails shining a beam of X-rays on to the crystal and measuring the depth and path of the scattered X-rays. By analyzing the scattered X-rays, the crystal composition and orientation is often established.
You should consider the wavelength and ability of your respective laser resource and decide on a crystal that is clear within the presented wavelength and might withstand the laser ability. And lastly, other components like the thermal steadiness, optical homogeneity, and nonlinear optical coefficient of the crystal also have to be regarded as.
Lithium triborate (LBO) nonlinear crystal is One of the more applied crystal for harmonics era for brief and extended pulse purposes. Due to it’s fairly smaller walkoff angle lengthy crystals can be made use of what allows to attain significant conversion performance. A Exclusive case of LBO crystal application is really a non-important stage matching (NCPM) for harmonics generation.
XRD will also be made use of to determine the crystal high-quality and defects inside the crystal, which include twinning and dislocations.
Almost all of the normal nonlinear crystals like BBO, LBO, BiBO or KTP for frequency doubling, tripling and quadrupling of the elemental laser radiation can be found from stock. Shopper-distinct Proportions and AR coatings can also be offered at competitive prices.
The characterization of LBO nonlinear crystals is essential for being familiar with their Houses and optimizing their overall performance in numerous apps. This chapter discusses different characterization approaches used for LBO nonlinear crystals.
Optical microscopy can be utilized to recognize area defects, for example scratches, cracks, and pits, that will impact the effectiveness in the crystal in numerous applications. Optical microscopy will also be employed to find out the crystal thickness and uniformity.
GWU-Lasertechnik features all conventional nonlinear crystals like LBO, BBO and KTP that has a broad selection of specifications. Beside the well-set up supplies, innovative crystals like CLBO or BiBO with remarkable Homes for e. g. deep-UV generation or superior-power ultrashort pulse lasers can be obtained. It doesn't matter if specific parts for R & D reasons are needed or cost-successful numbers in smaller, medium or big batches with in-time shipping for the manufacturing line are required: GWU’s committed company helps to locate the finest Main factors for the software.
Dust and stains on crystal surfaces can cause scattering/reduction of light and may even react with light to break click here optical surfaces in a significant incident laser electrical power.
Optical parametric amplification (OPA) is really a nonlinear method that involves the conversion of the higher-Electricity photon into two lower-Electrical power photons. LBO nonlinear crystals Use a superior nonlinear coefficient, which makes them ideal for productive OPA.
However, if the applying requires, these crystals may also face up to sure elevated tension conditions. It is usually recommended to consult which has a crystal skilled or make reference to distinct company pointers to find out the optimal problems in your precise LBO Crystal and software.
LBO includes a small susceptibility to dampness. End users are encouraged to deliver dry circumstances for both the use and preservation of LBO.
g. in the shape of “grey tracking�? This kind of phenomena are especially widespread for operation with ultraviolet mild. Observe that a gradual degradation can also lead into instantaneous catastrophic damage by way of extreme heat generation.
Crystal advancement is usually a significant move inside the production of superior-good quality LBO nonlinear crystals. The choice of crystal advancement strategy can considerably effects the crystal good quality and optical properties with the resulting crystal. The Czochralski, flux, and TSSG strategies are the most commonly utilised procedures to the creation of LBO nonlinear crystals, Every with its positives and negatives.
