The KTP crystal can be a nonlinear optical product that could transform the frequency of light. The KTP crystal is Slice and oriented in this kind of way that it satisfies the phase matching ailment for next harmonic era (SHG), which implies that two photons of the input beam can combine to produce just one photon of twice the frequency (or fifty percent the wavelength) at 532 nm (green).
The latter include Nd:YAG and also other neodymium-doped lasers. (Call us to request certain facts on our KTP to view if it is true for the software.)
Like a lot of crystal designations, People are both equally mongrelizations of chemical formulae and symbols and abbreviations. Potassium titanyl phosphate is most the right way KTiOPO4. Purpose adequate to connect with it just KTP.

“New�?electro-optical (EO) crystals are hard to find, “previous�?EO crystals are scarce and every has its own troubles, and the desire for high-general performance EO crystals by bigger energy, greater repetition amount, and narrower pulse width laser is real looking and urgent. The EO effectiveness of KTP was regarded as soon as it had been uncovered, but after greater than forty many years of growth, the reports, and items of EO equipment dependant on KTP are below People of other EO crystals, even though KTP is currently Just about The most cost effective nonlinear optical crystal materials. On this paper, determined by our understanding of the crystal composition of predecessors and ourselves, especially the understanding and exercise of quasi-one particular-dimensional ionic conduction mechanism, we believe that crystal progress is the most important rationale that has an effect on the controllability of crystal efficiency.
We choose the highest good quality content by SHG effectiveness mapping of every crystal. Fine surface area sharpening and twin band AR coatings with extremely very low losses allow for EKSMA Optics to provide KTP crystals appropriate for intracavity SHG software.
Also, the Currie temperature Tc of KTP is higher as opposed to response temperature for hydrothermal expansion. On the contrary, the growth temperature of your flux process generally needs to exceed Tc, KTP loses the uniformity of its ferroelectric domains, and electron dipole movement gets to be random. This process is demonstrated by the lack of the SHG alerts click here at and beyond the ferroelectric phase changeover (Curie) temperature. Consequently, flux growth results in multi-domain52,96 KTP crystals. Several experiences describe the various initiatives expended to control the area boundaries of KTP50,51,97.
Even so, sizeable linear EO coefficients and small dielectric constants32, which make KTP beautiful for EO programs for example EO modulators and Pockels mobile (Computer), haven't been nicely explored for product purposes. A particularly important benefit of KTP crystals in useful electro-optical programs could be the secure Bodily Houses. Its dielectric constant and electro-optic coefficient are insensitive to frequency, which allow it to be has fantastic frequency balance. Its electro-optic coefficient is insensitivity to temperature, which led a well temperature security. Furthermore its piezoelectric coupling result is weak, which ensure the sensor stable within the products with a lot more vibration.
For the duration of the last few many years, potassium titanyl phosphate (KTP) and its isomorphs have attracted a great deal of attention, largely due to their application in a variety of types of photonic gadgets. These components possess significant nonlinear optic and electro-optic coefficients, high optical destruction threshold, as well as broad thermal and angular acceptance for next harmonic generation.
Use the wonderful hurt threshold, harmonic conversion performance, and period-matching variety of Borate crystals for frequency multiplication in lasers and amplifiers. Find out more
Far better optical inhomogeneity can Increase the extinction ratio of EO change and beam high-quality on the laser. These are generally the demands during the purposes of KTP. On top of that, we located some variations with classic awareness in the particular analysis method. We've got also noticed that static pressure depolarization is a problem in KTP, in contrast to in DKDP and z-axis LN.
This Particular Challenge will address a wide array of topics related to KTP crystals: from very last achievements in crystal growth, enhancement of the gray-track resistance, and analyze in their piezoelectric, ferroelectric, electrooptical, and nonlinear-optical Attributes to varied photonic applications in broad spectral vary from in close proximity to UV to THz.
The horizontal axis may be the calendar year, plus the vertical axis may be the interior diameter with the autoclave. The dimensions of your crystal is largely based on the interior diameter from the autoclave, so it truly is mentioned jointly from the graph, marked which has a good symbol to differentiate it with the hollow image representing the internal diameter with the autoclave.
