The KTP crystal is really a nonlinear optical material that will convert the frequency of light. The KTP crystal is Slice and oriented in this kind of way that it satisfies the period matching issue for 2nd harmonic era (SHG), which implies that two photons with the input beam can Mix to create one particular photon of twice the frequency (or half the wavelength) at 532 nm (green).
EKSMA Optics takes advantage of cookies to give you the ideal searching knowledge. Should you keep on to work with our providers, We'll assume that you just agree to using these kinds of cookies.
And be assured that any time you choose GAMDAN Optics KTP crystals, you’re deciding upon optical crystals of Excellent good quality, produced inside the USA. As well as they boast a wide array of other appealing qualities which includes minimal absorption, higher harm threshold, and durability.
Passions: ferroelectrics; domain composition; domain engineering; nonlinear optics; nanotechnology; light-weight frequency conversion
“New�?electro-optical (EO) crystals are difficult to find, “aged�?EO crystals are scarce and every has its very own troubles, and also the demand for top-performance EO crystals by greater electricity, larger repetition price, and narrower pulse width laser is real looking and urgent. The EO efficiency of KTP was regarded when it was found out, but soon after greater than 40 decades of growth, the experiences, and merchandise of EO gadgets depending on KTP are fewer than Individuals of other EO crystals, Regardless that KTP has become Nearly The most cost effective nonlinear optical crystal material. In this particular paper, based upon our idea of the crystal composition of predecessors and ourselves, especially the being familiar with and practice of quasi-1-dimensional ionic conduction system, we believe that crystal development is The key reason that impacts the controllability of crystal overall performance.
KTP crystal (Potassium Titanyl Phosphate) is a superb and but reasonably priced non-linear crystal gives A variety of distinctive attributes:
KTP crystals are optimized for SHG intracavity configuration in reduced peak power CW lasers. Due to the big number of passes through the crystal, very low insertion losses and superior homogeneity are essential for conversion performance.

11a), and the other is to work with The 2 crystals orthogonally (Fig. 11b, c). The latter is the most applied technique for many commercial merchandise, when our KTP-based EO switch solutions also hire this product, as revealed in Fig. 11d, e. Specifically, the same old way of compensating for This is certainly to employ a set of crystals, matched in optical thickness, that's then their utilized electric fields orientated at 90° relative to each other such that light-weight is polarized together the x or y-axis say in the main crystal is then polarized alongside the z-axis of the second crystal. The “slow�?ray in the very first crystal then becomes the “speedy�?ray in the 2nd and the whole static birefringence is Hence in idea canceled inside the composite crystal pair.
It really is used in surgical lasers, in which selective absorption lets medical ablation while steering clear of damage to adjacent tissue. More exclusively, the green light-weight made by KTP is used for doing some varieties of prostate surgical procedures.
All manuscripts are completely refereed by way of a one-blind peer-review method. A tutorial for authors and various pertinent data for submission of manuscripts is available within the Instructions for Authors site.
The recent fascination in growing the frequency conversion performance by periodical poling making use of modern methods of micro- and nanodomain engineering during the crystals of KTP household is gigantic.
Through a series of science and technological know-how, we understand The expansion of huge-sizing crystals with higher-optical uniformity, then decrease the absorption of KTP to an exceptionally reduced degree, click here and expand crystals with resistance to electrical problems and laser problems. On this foundation, lessening the conductivity and improving the uniformity of optical, electrical, piezoelectric, and ferroelectric properties are emphasized. The extinction ratio, piezoelectric ringing effect, and thermal impact of your EO swap dependant on KTP crystal are analyzed, plus some publicly out there development of employing KTP EO units in large-repetition price laser is stated. Eventually, we're looking ahead to the event of KTP EO crystal with the laser technique to EO generator for integrated optics.
