KTP crystals and particular other materials contain the seemingly magical capacity to alter the wavelength of light. KTP crystals are most often used to convert 1 micron wavelength invisible infrared light-weight into visible green light-weight.
The latter involve Nd:YAG and also other neodymium-doped lasers. (Call us to ask for certain information on our KTP to check out if it is correct to your application.)
Ultra high quality KTP has a mix of appealing properties: large hurt threshold, high nonlinear coefficients, huge acceptance angle, and large conversion effectiveness approximately about 60%.
Viewed by 3608 Abstract Scientific studies of polarization reversal processes in potassium titanyl phosphate (KTiOPO4, KTP) solitary crystals with floor dielectric layer are very important due to their potential applications as The idea of bottom-up engineering for creation of periodically poled nonlinear-optical crystals. We current the final results [...] Read a lot more. Experiments of polarization reversal processes in potassium titanyl phosphate (KTiOPO4, KTP) solitary crystals with floor dielectric layer are crucial because of their probable apps as the basis of base-up technological innovation for creation of periodically poled nonlinear-optical crystals. We current the results of switching currents Investigation accompanied by in situ visualization of domain kinetics all through polarization reversal in KTP with three m-thick photoresist dielectric layer. Qualitative alter from the switching existing shape has long been uncovered as compared to the polarization reversal without the need of area dielectric layer.
PDF KTP (Potassium titanyl phosphate) can be a nonlinear crystal generally Employed in extracavity configuration when only one pass through the crystal is required.
A lot of metals reflect the 1.06 micron radiation of superior energy Nd:YAG lasers, still absorb the frequency doubled inexperienced light-weight, so slicing and welding can be done proficiently.
Lasers with chopping-edge performance and industrial reliability from your pioneer in ultrafast lasers. Recover facts more rapidly and publish additional.

11a), and the opposite is to employ the two crystals orthogonally (Fig. 11b, c). The latter is easily the most employed approach for many professional solutions, while our KTP-primarily based EO switch products also employ this model, as shown in Fig. 11d, e. Precisely, the same old way of compensating for this is to use a pair of crystals, matched in optical thickness, and that is then their utilized electric fields orientated at ninety° relative to one another this sort of that mild is polarized along the x or y-axis say in the primary crystal is then polarized together the z-axis of the 2nd crystal. The “sluggish�?ray in the very first crystal then turns into the “rapidly�?ray in the next and the whole static birefringence is As a result in theory canceled within the composite crystal pair.
It is generally believed that the Actual physical Homes of H-KTP go through to be a byproduct of its expansion system.
fifteen g/one hundred mL/ten °C). The addition of 0.one mol·L−one KH2PO4 can inhibit the development of impurity K2Ti6O13 and make sure the considerable solubility of KTP In this particular system80. Moreover, to regulate the method’s redox probable, the oxidant H2O2 was additional to lessen the probability of VO2+, that's considered to become the main reason for “Gray-keep track of�?harm and electro-chromic result damage80. Commonly, favorable dissolution and progress zone temperatures for scale-up transportation reactions are gleaned with the solubility analyze. Extra importantly, unfavorable temperature zones are discarded from the response plan to preserve time and resources.
If the KTP crystal is applied being an EO modulator, the used electrical field is parallel to the z-axis, and The sunshine propagation route is parallel for the y-axis or x-axis. If a comparatively reduced flip-off voltage is desired, a y-axis change is necessary. In observe, extended x-axis switches click here in many cases are utilised to acquire the specified reduced turn-off voltage for crystal advancement economics. The E-O coefficient of the H-KTP crystal may be decided as adhere to in Desk 3. Our EO coefficient measurement success at 632.8 nm are consistent with the 1986 examination effects utilizing the hydrothermal process KTP32.
While the adoption with the flux approach for KTP rising has performed a essential role in the sensible software of nonlinear optical crystals, Specially the recognition of inexperienced good-state lasers in intake and processes. Also, LiB3O5 (LBO)seventy two and β-BaB2O4 (BBO)seventy three are generally used nonlinear optical crystals grown by flux process. The flux method has played an irreplaceable function in the fabric preparing of nonlinear optical crystals. Concurrently, these 3 nonlinear optical crystals, in turn, the flux strategy, retains their standing as A vital strategy for industrial crystal expansion. The numerous benefit of the flux approach is the fact crystal expansion is usually obtained under ambient pressure. Nine many years after the hydrothermal growth of Rb1−xKxTiOPO4 (1.0 ≥ x ≥�?), RKTP crystal was very first claimed, and flux technique happen to be used by groups in both of those the Soviet Union74 and China75,76. Crystal size is no more the obstacle to EO units fabricated by F-KTP71. Once the flux strategy grows crystals of enough sizing, the EO properties and EO applications of F-KTP have also been researched.
One or more openings of a selected diameter are reserved to slow down the dopant. It communicates Using the substances in The complete program to realize the sluggish launch of trace amounts of doping. We seek advice from this technological innovation in addition to a series of supporting technologies, like the micro-doping sustained-launch hydrothermal know-how (MSHT). Right after adopting this technology, the σ33 uniformity on the crystal is enhanced, Therefore noticeably expanding the accomplishment rate of EO crystal pairing into EO Q-switches from 50% to about 75%.
