RTP, Rubidium Titanyl Phosphate, RbTiOPO4-manufacture,factory,supplier from China

RTP crystal is widely used for Electro-Optic applications whenever low switching voltages are required. e.g. in laser Q-switching system with high frequency repetition, high power and narrow pulse width. RTP E-O devices are not only used in laser micromachining and laser ranging, but also in major scientific exploration projects due to their excellent comprehensive performance.As RTP is transparent from 400nm to 3.5µm, it can be used in multiple types of laser such as Er:YAG laser at 2.94µm with fairly good efficiency.

RTP (Rubidium Titanyl Phosphate - RbTiOPO4) is a robust crystal material suitable for a wide range of E-O applications. It has advantages of higher damage threshold (about 1.8 times that of KTP), high resistivity, high repetition rate, no hygroscopic or piezoelectric effect.

RTP (Rubidium Titanyl Phosphate - RbTiOPO4) is a very desirable crystal material for E-O modulators and Q-switches. It has advantages of higher damage threshold (about 1.8 times that of KTP), high resistivity, high repetition rate, no hygroscopic or piezoelectric effect. As biaxial crystals, RTP’s natural birefringence needs to be compensated by use of two crystal rods specially oriented so that beam passes along the X-direction or Y-direction.

RTP (RbTiOPO4) is an isomorph of KTP crystal. RTP single crystals are grown in WISOPTIC by a slow-cooling flux method.

RTP possesses a large electro-optic impact for light propagating along either the x or y direction (electric powered along z). It functions right optical transparency from around 400nm to over 4µm. RTP offers a high resistance to optical damage with energy ~1Gw/cm2 for 1ns pulses at 1064nm. It is largely total lack of piezo-electric resonances at 200kHz and probable beyond. The primary distinction between RTP and BBO whilst used for Q-switching pertains to the common power degree at which the Q-switch is capable of be used practically.

Potassium Dihydrogen Phosphate (KDP) and Potassium Dideuterium Phosphate (KD*P, DKDP) crystals are among the most widley used nonlinear crystals. Both of these crystals are routinely used for the doubling, triplingand quadrupling of Nd:YAG lasers at room temperatures.

Potassium Dihydrogen Phosphate (KDP) and Potassium Dideuterium Phosphate (DKDP) are among the most widely-used commercial NLO materials, characterized by good UV transmission, high damage threshold, and high birefringence, though their NLO coefficients are relatively low. They are usually used for doubling, tripling or quadrupling of a Nd:YAG laser (at constant temperature).

Characterized by the excelent UV transmission, high damage threshold, and high birefringence, KDP (Potassium Dihydrogen Phosphate)  and KD*P (Potassium Dideuterium Phosphate) are useful commercial NLO materials for doubling, tripling and quadrupling of Nd:YAG laser at room temperature or an elevated temperature. They are also excellent electro-optic (EO) crystals with high electro-optic coefficients, widely used as electro-optical modulators and Pockels cells for Q-switched lasers.

Potassium dihydrogen phosphate KH2PO4 (KDP) is a transparent dielectric material best known for its nonlinear optical and electro-optical properties. Because of its nonlinear optical properties, it has been incorporated into various laser systems for harmonic generation and optoelectrical switching.

Characterized by the excelent UV transmission, high damage threshold, and high birefringence, KDP (Potassium Dihydrogen Phosphate) are commonly used commercial NLO materials for doubling, tripling and quadrupling of Nd:YAG laser at room temperature or an elevated temperature. KDP are also excellent electro-optic (EO) crystals with high EO coefficients, thus popularly used as EO modulators and Pockels cells for Q-switched lasers.

    Potassium dideuterium phosphate DKDP (KD * P) crystal has low optical loss, high extinction ratio, and excellent electro-optical performance. DKDP Pockels cells are made by using the longitudinal effect of DKDP crystals. The modulation effect is stable and the pulse width is small.

E-O Q-switch based on DKDP (KD*P) crystals are one of the most popular Pockels cells in the market.Deuterated potassium dihydrogen phosphate has good transmission from 390 nm to 1400 nm (0.39 μm – 1.4 μm) and combined with high electro-optical coefficients makes it suitable for Pockels cells.Highly deuterated DKDP (D>99% – WISOPTIC) is necessary to reach effective electro-optical response.

KTP Pockels are based on hydrothermal-grown high resistivity KTP crystals overcomes the common electrochromism damage of flux-grown KTP. Hydrothermal-grown KTP crystals have better optical homogeneity and higher damage threshold comparing to RTP crystals. This KTP crystal has large effective electro-optic coefficients and lower half-wave voltage. The Q-switch is built utilizing thermally compensated double crystal designs.

An aspherical lens features a non-spherical but rotationally symmetric shape with a curvature radius that changes at various points between the center and the edge. Although producing this type of lens is difficult, when manufactured properly, it offers greater functionality than a comparable spherical lens.Spherical Lenses vs. Aspherical LensesSpherical lenses have a spherical surface and the same radius of curvature across the entire lens. In contrast, aspherical lenses have a more complicated surface with a gradually changing curvature from center to edge.

LiNbO3 (Lithium Niobate, LN) crystal is a multifunctional material that integrates properties of piezoelectric, ferroelectric, pyroelectric, nonlinear, electro-optical, photoelastic, etc. LiNbO3 has good thermal stability and chemical stability.Among the EO crystals, LN and DKDP are the two primary material that have been practical. DKDP crystals can be easily grown with a high optical homogeneity, which can satisfy the requirement of a large caliber Pockels cell.

Pure LiNbO3 (LN) is a good candidate for various optical devices, but has a major disadvantage due to its low threshold optical damage. MgO:LN (congruent compositions) is one of the possible solutions to deal with this problem. MgO doping has played an important role in LN and shown an increased threshold laser beam strength by 100 times. An interesting point is that every physical property of MgO:LN (e.g.
