New Step by Step Map For BBO Crystal

Non-linear Optical (NLO) crystals provide an enormously adaptable Remedy for creating new wavelengths from current, off-the-shelf laser resources. The optical wavelength spectrum is used by a significant and frequently increasing number of applications, from manufacturing of professional medical lasers, quantum networking & computing by means of to environmental sensing along with a lot of Other people.
Having said that, it’s crucial that you Notice that although BBO crystals can transmit UV light, they ought to be handled with care when used in UV apps to circumvent likely harm to the crystal and ensure safety.
The temporal stroll-off of your slower pulse with regard on the more quickly could be a substantial portion of the pulse period. This is often illustrated in Figure 22.
The stage-matching abilities of BBO crystals are worthy of Unique mention. Inside the intricate dance of photons, where by conversion from 1 wavelength to a different is usually ideal, the period-matching offered by BBO makes sure that Electrical power losses are minimal.
You should use "Add to Cart" to place the attention-grabbing items during the shopping cart. Look at with on the net payment or inquire us for the prices/availability by using the procuring cart.
If the crystal surfaces remain “dirty�?just after the above cleaning techniques, the surfaces may have been broken. Please Get hold of us for rework with the crystals.
The majority of the standard 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-unique Proportions and AR coatings also are provided at aggressive rates.
Figure fifteen exhibits the orientation of γ in a laboratory body rotation of the crystal. In this instance circumstance, the nonlinear crystal is mounted in an RSP1 rotation mount in addition to an RP01 rotation stage. Improvements in γ and θ alter the orientation from the optic axis, . In such a case, adjustments in γ are already used to align Together with the horizontal plane and among the theory common axes vertically. For a vertically polarized input beam, this orientation will allow the rotation stage for use to regulate θ.
BBO crystals are delicate and need cautious handling to avoid damage to their surfaces. They should be taken care of with clear, lint-free of charge gloves to prevent scratching or contaminating their surfaces. When not in use, BBO crystals need to be saved in the amazing, dry place clear of direct sunlight, as extended exposure to heat and light-weight can degrade their optical Attributes.
GWU-Lasertechnik gives all conventional nonlinear crystals like LBO, BBO and KTP that has a broad number of technical get more info specs. Beside the properly-founded components, innovative crystals like CLBO or BiBO with remarkable Attributes for e. g. deep-UV era or superior-electricity ultrashort pulse lasers are available. It does not matter if person items for R & D applications are expected or Charge-effective quantities in small, medium or big batches with in-time shipping for the creation line are necessary: GWU’s committed assistance really helps to locate the greatest core factors in your software.
Dust and stains on crystal surfaces may cause scattering/reduction of light and can even respond with light to break optical surfaces in a large incident laser ability.

And finally, spectroscopy, the examine of interactions amongst issue and electromagnetic radiation, tremendously Rewards from the 266nm technology. In spectroscopic apps, diverse wavelengths of light interact otherwise with supplies, offering a spectrum which can be analyzed to determine the fabric’s Homes or composition.
The duration from the SHG crystal appreciably affects the spectral width on the reference pulse, or alternatively the bandwidth of your SHG filter.
