LBO has this kind of great transmittance that it may even be utilized to produce 266 nanometer mild, Even though the absorption down below 300nm is mostly too superior with the conversion being valuable. Additionally, it shows Great efficiency for frequency conversion usually.
Filters down below or the shape at the bottom can be employed to help item research or make additional inquiries.
Very last although not least, superior optical homogeneity guarantees uniform light-weight propagation with the crystal, leading to far better beam excellent and less distortions.
Finally, once the crystal has grown to the specified size, it truly is harvested, Minimize, polished, and coated according to its intended software. This arduous and exacting process ends in an LBO Crystal that strikes a great stability amongst size and high quality, manifesting the extraordinary optical Attributes that these crystals are celebrated for.
The commonest utilization of LBO is In brief pulse, substantial pulse level lasers; the upper power density the greater. It is also very well suited for non-critical phase matching (NCPM) for frequency conversion of CW and quasi-CW radiation, at 90% conversion performance with out walk-off.
Optical microscopy can be utilized to identify area defects, including scratches, cracks, and pits, that may have an affect on the effectiveness from the crystal in a variety of applications. Optical microscopy can be used to ascertain the crystal thickness and uniformity.
Too much optical intensities all through operation may instantly destruction a crystal. Regretably, nonlinear crystals generally must be operated not far from their optical damage threshold to obtain a adequately higher conversion performance. This means a trade-off among conversion efficiency and crystal lifetime.
If the crystal surfaces are still “dirty�?soon after the above mentioned cleaning processes, the surfaces may need been damaged. Be sure to Call us for rework of your crystals.
Borates for instance LBO and BBO also do the job perfectly in broadly tunable optical parametric oscillators and website optical parametric chirped-pulse amplification.
Even so, if the appliance needs, these crystals may also withstand particular elevated force circumstances. It is always suggested to consult having a crystal professional or make reference to particular company rules to ascertain the best ailments in your distinct LBO Crystal and software.
The magnitude from the successful nonlinear coefficient depends upon the nonlinear tensor factors and about the used phase-matching configuration. A substantial nonlinearity is essential particularly Should the achievable optical intensities are minimal.
Optical crystals can show various sorts of optical nonlinearities, which may be used in many means:
LBO nonlinear crystals have exclusive Attributes that make them ideal for various apps in optics and photonics. This chapter discusses many of the commonest apps of LBO nonlinear crystals.
