KTP crystals and specified other products provide the seemingly magical capability to alter the wavelength of sunshine. KTP crystals are most frequently used to convert 1 micron wavelength invisible infrared light into noticeable green light-weight.
The latter include things like Nd:YAG together with other neodymium-doped lasers. (Get hold of us to request particular information on our KTP to determine if it is true to your software.)
Ultra high quality KTP has a mix of fascinating Qualities: high hurt threshold, substantial nonlinear coefficients, big acceptance angle, and superior conversion efficiency as many as about 60%.
Optical Homogeneity of H-KTP (a) and H-RKTP (b); c Conoscopic interference image of a H-RKTP EO change. Piezoelectric coefficient d33 distribution of d H-KTP and e H-RKTP; f twenty wafers by using a thickness of 1 mm along the z-airplane from starting to stop for confirming the ferroelectric domain on the crystal by measuring the piezoelectric coefficient d33; Distribution of DC conductivity at 70 °C of H-RKTP crystal g by classic hydrothermal approach and h micro-doping sustained-launch hydrothermal technologies (MSHT)
PDF KTP (Potassium titanyl phosphate) is a nonlinear crystal mostly used in extracavity configuration when only one go through the crystal is necessary.
KTP crystal (Potassium Titanyl Phosphate) is a wonderful and still reasonably priced non-linear crystal provides A selection of distinctive options:
KTP crystals are optimized for SHG intracavity configuration in lower peak energy CW lasers. A result of the massive quantity of passes through the crystal, very low insertion losses and high homogeneity are important for conversion effectiveness.
The Nd:YVO4 crystal is Reduce and oriented in this type of way that it satisfies the polarization ailment for efficient lasing. The Nd:YVO4 crystal is additionally temperature-stabilized by a thermoelectric cooler (TEC) to keep up its ideal efficiency.
The laser diode is a tool that emits a laser beam having a wavelength of 808 nm (infrared) and an influence of 2 W. The laser diode is used for a pump source for your Nd:YVO4 crystal, which happens to be a laser obtain medium that can amplify mild at 1064 nm (infrared).
It is mostly thought that the Actual physical properties of H-KTP suffer to be a byproduct of its progress course of action.
2). Additionally, the A+ ions could be distributed in media far more complicatedly with various (nearly five) positions of varied occupancies. Simultaneously, depending upon the nature of A and M metals, The form and sizing of such voids can a little fluctuate and a number of other nearby Vitality minima can type accounting for the splitting of your A+ web-sites above two sub-websites symmetrically with equivalent occupancy (Fig. 2) or asymmetrically. We found which the KTP crystal will decompose after a duration of the large electric powered discipline is used. Suppose the K+ ions have been substituted absolutely by other monovalent cations, the isomorphs. Fedotov et al.65 supplied the assumption the A+ cation performs a crucial position in stabilizing this 3D structural framework.
This Unique Situation will address a wide array of subject areas associated with KTP crystals: from previous achievements in crystal expansion, advancement of The grey-keep track of resistance, and study in their piezoelectric, ferroelectric, electrooptical, and nonlinear-optical properties to numerous photonic purposes in wide spectral range between near UV to THz.
When operated inside a thermally compensated manner, excellent Q-switching properties are demonstrated with KTP crystals in a very thermally compensated mode30. Salvestrini et al. take a comparative analyze of five nonlinear optical crystals for EO Q-switching of laser resonators. KTP displays the highest values with the EO application’s advantage figures, which includes driving voltage, switching velocity, and piezoelectric ringing (PER)77. Sad to say, due to the rather large conductivity, when File-KTP was made use of as being a high common electric power EO swap, electrons injected at the anode from the more info crystal can reduce the stoichiometric Ti4+ ions from the crystal lattice to Ti3+, even if F-KTP developed at temperature constant is used as opposed to standard the temperature drop flux method78. Upon implementing An electrical discipline, a black absorbing band moves with the anode toward the cathode from the F-KTP, compromising its utility as being a Q-swap. This phenomenon is definitely the electro-chromic problems stated previously mentioned.
In 2024, the French-German MERLIN satellite (Methane Distant Sensing Lidar Mission) will go into Earth orbit to measure concentrations of atmospheric methane with unprecedented precision and so much better have an understanding of the sources of this greenhouse gasoline participating in a crucial function in world wide warming117. For that frequency conversion for the absorption line of methane, an OPO of KTP is carried out in MERLIN. It is made of two KTP crystals in a ring resonator, as well as the output Vitality�?9 mJ, the wavelength at about 1645 nm in an individual pulse, and spectral purity >99.
