LBO Crystal - An Overview
LBO Crystal - An Overview
Blog Article
Crystal life time can be strongly depending on the material good quality, although specified degradation phenomena seem like intrinsic limits of the material.
Although the crystal content or coating is not delicate to drinking water, smaller drinking water droplets could focus laser radiation far more tightly than underneath standard operation, and therefore injury the crystal content.
LBO Crystals sustain their security beneath many different situations, demonstrating their versatility and resilience. Nevertheless, their exceptional performance is commonly attained below certain temperature and force parameters.
GWU-Lasertechnik has greater than 30 a long time of knowledge in distributing laser crystals. Decide on GWU to get pleasure from our extensive expertise and in-industry encounter!
Almost all of the common nonlinear crystals like BBO, LBO, BiBO or KTP for frequency doubling, tripling and quadrupling of the fundamental laser radiation can be obtained from inventory. Buyer-specific dimensions and AR coatings are provided at competitive charges.
The choice of the most suitable crystal material for a given application is frequently far from trivial; it should really contain the thing to consider of many facets. By way of example, a large nonlinearity for frequency conversion of ultrashort pulses would not support In case the interaction length is strongly minimal by a big group velocity mismatch more info and the small hurt threshold boundaries the relevant optical intensities.
LBO can achieve both equally temperature NCPM and spectral NCPM (with a very extensive spectral bandwidth) at 1300 nm. This is often favorable for the SHG of extremely broadband or ultrafast pulses at ~ 1300 nm.
Further enriching their optical enchantment is definitely the broad acceptance angle. This characteristic allows for much more significant gentle interaction and minimizes the necessities for beam alignment, simplifying the overall Procedure.
The idea of these Attributes is essential for planning and increasing significant-quality LBO nonlinear crystals for numerous applications
Shorter wavelength gentle with greater energy pulses provides enhanced precision and smaller location size than industrial power neodymium or CO2 lasers, thus attaining finer resolution and precision.
Even so, if the appliance requires, these crystals also can stand up to particular elevated force conditions. It is usually suggested to consult which has a crystal qualified or confer with distinct maker pointers to find out the best ailments for your particular LBO Crystal and software.
Probably the most prevalent purposes is frequency doubling, exactly where LBO Crystals competently convert the frequency of a superior power laser, efficiently halving the wavelength and opening up a spectrum of prospects for laser purposes.
PL spectroscopy can be employed to discover impurities and defects in LBO nonlinear crystals that will have an effect on their effectiveness in many apps. PL spectroscopy will also be employed to ascertain the crystal excellent and homogeneity.
Crystal advancement is usually a important action within the production of high-high-quality LBO nonlinear crystals. The selection of crystal development technique can appreciably effect the crystal high quality and optical properties with the resulting crystal. The Czochralski, flux, and TSSG solutions are the mostly applied strategies to the production of LBO nonlinear crystals, Every single with its benefits and drawbacks.
