If you don't locate the ideal solutions over, you may let's know your needs or applications in the shape below. Our product sales or specialized staff members can get back again for you as quickly as possible.

Additionally, it has an essential software in economical technology of ultrabright entangled photons through blue pumped spontaneous parametric down conversions (SPDC).

five mm to minimize group velocity mismatch and are ideal for frequency doubling or tripling of Ti:sapphire and Yb:doped laser pulses. The significant and noncritical stage matching LBO crystals are ideal for 2nd or 3rd harmonic era of Nd:YAG and Yb:doped lasers.

BIBO crystals can be employed as significant-effectiveness frequency doubling and frequency summing devices and also have broad software prospects in optical parametric oscillation (OPO).

Regardless of whether the crystal substance or coating will not be delicate to water, little water droplets may perhaps focus laser radiation more tightly than underneath usual operation, and thus harm the crystal material.

Lithium niobate (LiNbO3) and lithium tantalate (LiTaO3) are components with a relatively robust nonlinearity. They are sometimes employed for nonlinear frequency conversion and likewise for electro-optic modulators. Equally components are available in congruent As well as in stoichiometric kind, with essential differences relating to periodic poling and photorefractive results (see down below). Lithium niobate and tantalate are classified as the most often utilised materials while in the context of periodic poling; the ensuing supplies are identified as PPLN (periodically poled lithium niobate) and PPLT, respectively, or PPSLN and PPSLT for the stoichiometric versions.

Bismuth Triborate (BiB3O6 or BIBO) can be a newly made nonlinear optical crystal. It possesses huge efficient nonlinear coefficient, large damage threshold and inertness with respect to humidity.

In the case of ultrashort pulses the high team velocity mismatch enforces the usage of a shorter crystal, which needs higher optical intensities for a specified conversion effectiveness.

the chemical toughness; e.g., some crystal materials are hygroscopic, Other individuals bear chemical changes when heated inside a vacuum chamber for software of the dielectric coating

  )  to blow off dust together with other loose contaminants very first. If a dry nitrogen line is offered while in the lab, an air gun can be utilised  to blow away dust particles. Blow off the surface area Carefully. Tend not to blow off the crystal by itself from a hand!

The load of your solvent will induce the lens tissue to come into connection with the crystal surface. Slowly and gradually but steadily drag the damp lens tissue through the crystal area getting watchful to not elevate the lens tissue off on the floor. Keep on dragging the lens tissue until eventually it can be off of your area.

The magnitude with the successful nonlinear coefficient is dependent upon the nonlinear tensor components and to the utilized period-matching configuration. A higher nonlinearity is crucial specially Should the website achievable optical intensities are minimal.

Since the second harmonic (SHG) is usually widely accustomed to make coherent noticeable light-weight and ultraviolet radiation, individuals listen to it, but the standard nonlinear crystals such as KDP, LBO, KTP, B-BBO even have many shortcomings. BIBO crystal is a fresh kind of nonlinear crystal. In contrast with KDP crystal, it would make up for your disadvantage that KDP crystal can increase in substantial sizing but dissolve in h2o.
