The 5-Second Trick For LBO Crystal
Blog Article
The knowledge and application of these strategies are critical for the event and optimization of varied nonlinear optical products and apps.
LBO has these great transmittance that it may even be accustomed to make 266 nanometer gentle, Even though the absorption underneath 300nm is mostly much too significant for that conversion to generally be practical. In addition it shows Great effectiveness for frequency conversion on the whole.
Lithium triborate (LBO) nonlinear crystal is Among the most made use of crystal for harmonics era for brief and long pulse purposes. On account of it’s reasonably little walkoff angle lengthy crystals might be applied what lets to accomplish significant conversion performance. A Exclusive scenario of LBO crystal software is usually a non-vital phase matching (NCPM) for harmonics technology.
The flux strategy allows for the creation of significant LBO crystals with reduced defect density and higher optical high quality. The use of a flux may help to lower impurities and defects during the crystal, leading to improved crystal high-quality.
Each have a relatively minimal hurt threshold, but usually do not need to be operated at substantial intensities due to their higher nonlinearity. They have a bent for photorefractive consequences, which happen to be harmful for frequency conversion, but are utilized for, e.g., holographic facts storage in Fe-doped LiNbO3 crystals. The inclination for “photorefractive damage�?relies upon strongly on the material composition; e.g. it can be lowered by way of MgO doping and by utilizing a stoichiometric composition.
The most typical utilization of LBO is Briefly pulse, large pulse level lasers; the upper power density the higher. It is additionally incredibly well here matched for non-crucial stage matching (NCPM) for frequency conversion of CW and quasi-CW radiation, at 90% conversion efficiency with out wander-off.
LBO can attain the two temperature NCPM and spectral NCPM (with a really wide spectral bandwidth) at 1300 nm. This can be favorable for that SHG of very broadband or ultrafast pulses at ~ 1300 nm.
GWU-Lasertechnik presents all conventional nonlinear crystals like LBO, BBO and KTP by using a wide number of requirements. Beside the well-established materials, impressive crystals like CLBO or BiBO with fantastic properties for e. g. deep-UV technology or significant-power ultrashort pulse lasers are available. Irrespective of if unique parts for R & D needs are demanded or Price-economical numbers in small, medium or large batches with in-time shipping and delivery to the production line are wanted: GWU’s committed provider helps you to find the most effective Main components for the software.
Our crystals are Utilized in an array of programs, including various styles of nonlinear frequency conversion and electro-optics, but additionally quantum know-how.
Optical parametric amplification (OPA) is often a nonlinear process that includes the conversion of a high-Power photon into two reduce-Strength photons. LBO nonlinear crystals Use a significant nonlinear coefficient, which makes them perfect for effective OPA.
Lithium Triborate LiB305or LBO is a recently designed nonlinear optical crystal.It is exclusive in lots of areas,Primarily its large transprency assortment,reasonably high nonlinear coupling,higher hurt threshold and superior chemical and mechanical Qualities.
g. 20 μm. The group velocity mismatch while in the thicker substrate substance may well not make any difference, as the nonlinear interaction takes location only in the thin crystal. The substrate only serves to mechanically stabilize the thin nonlinear crystal.
) to blow off dust and various loose contaminants very first. If a dry nitrogen line is offered from the lab, an air gun may also be applied to blow absent dust particles. Blow off the area Carefully. Usually do not blow from the crystal alone from a hand!
They will endure considerable warmth without any considerable efficiency loss, making certain that the optical technique remains responsible and effective even in demanding eventualities.
