If you do not find the acceptable products above, you may allow us to know your needs or purposes in the shape beneath. Our income or technical staff will get again to you personally without delay.
Inertness to Dampness: BIBO crystal is inert to dampness, which implies it does not degrade or drop its optical Qualities when exposed to humidity. This helps make BIBO a more stable and reputable selection for optical purposes in many environments.
5 mm to reduce team velocity mismatch and are perfect for frequency doubling or tripling of Ti:sapphire and Yb:doped laser pulses. The essential and noncritical stage matching LBO crystals are perfect for second or 3rd harmonic era of Nd:YAG and Yb:doped lasers.
Typically, the crystal materials must have a superior optical transparency for all wavelengths concerned �?for example, for pump, sign and idler within an optical parametric amplifier.
Both equally have a comparatively reduced hurt threshold, but never must be operated at superior intensities because of their higher nonlinearity. They've a bent for photorefractive outcomes, which might be detrimental for frequency conversion, but are used for, e.g., holographic facts storage in Fe-doped LiNbO3 crystals. The inclination for “photorefractive destruction�?relies upon strongly on the material composition; e.g. it can be lessened by using MgO doping and by utilizing a stoichiometric composition.
Make sure you use "Include to Cart" to put the interesting goods during the purchasing cart. Have a look at with on the internet payment or ask us for the prices/availability via the buying cart.
Lithium niobate (LiNbO3) and lithium tantalate (LiTaO3) are materials with a relatively powerful nonlinearity. They will often be useful for nonlinear frequency conversion in addition to for electro-optic modulators. Each resources are available in congruent As well as in stoichiometric form, with vital dissimilarities concerning periodic poling and photorefractive effects (see down below). Lithium niobate and tantalate are definitely the most frequently utilized elements while in the context of periodic poling; the resulting resources are known as PPLN (periodically poled lithium niobate) and PPLT, respectively, or PPSLN and PPSLT with the stoichiometric versions.
Scientific investigation and progress: BIBO crystals also Enjoy a significant job in scientific investigate and enhancement. Its great nonlinear optical effectiveness presents new equipment and possibilities for ultrafast phenomenon investigate, sturdy area physics, biomedical imaging as well as other fields
rystal surface is horizontal and a little bit over your fingers. Take a refreshing, cleanse sheet of lens tissue and place it around the crystal. Ensure that the lens tissue is usually drawn through the crystal area. Upcoming, position a small drop of pure isopropyl Alcoholic beverages (IPA) on the lens tissue in addition to the crystal floor.
Crystals which might be non-critically section-matched in a crystal oven might exhibit difficulties once the crystal temperature is modified way too fast or too frequently. In particular, anti-reflection coatings might be broken as a consequence of distinctive thermal growth coefficients in the check here involved materials.
Non-linear Optical (NLO) crystals give an enormously adaptable Answer for making new wavelengths from present, off-the-shelf laser sources. The optical wavelength spectrum is utilized by a substantial and frequently increasing variety of applications, from production of clinical lasers, quantum networking & computing through to environmental sensing along with many Other people.
The burden of the solvent will induce the lens tissue to come into contact with the crystal surface. Slowly but surely but steadily drag the moist lens tissue throughout the crystal area getting very careful to not lift the lens tissue off of your surface area. Continue dragging the lens tissue until eventually it can be off in the area.
The magnitude on the productive nonlinear coefficient will depend on the nonlinear tensor parts and within the used stage-matching configuration. A superior nonlinearity is very important specifically Should the achievable optical intensities are lower.
flux-developed KTP and RTP with its superior nonlinearity, also in variants with high gray tracking resistance
