If you don't find the acceptable products and solutions above, you might let's know your needs or applications in the form underneath. Our gross sales or specialized staff members will get back for you at the earliest opportunity.
The latter include Nd:YAG together with other neodymium-doped lasers. (Call us to request precise facts on our KTP to determine if it is correct in your application.)
Extremely good quality KTP has a mix of attractive Attributes: high hurt threshold, substantial nonlinear coefficients, big acceptance angle, and substantial conversion efficiency as much as about 60%.

PDF KTP (Potassium titanyl phosphate) can be a nonlinear crystal typically Employed in extracavity configuration when an individual pass through the crystal is required.
Numerous metals reflect the one.06 micron radiation of superior ability Nd:YAG lasers, nonetheless take in the frequency doubled eco-friendly light-weight, so cutting and welding can be carried out effectively.
For normally paired KTP EO products, due to the sizeable thermo-optic coefficient of the KTP crystal, and the several Electrical power on the oscillating laser and pumping light absorbed by the back and front crystals, the thermal depolarization influence will occur under the situation of higher pumping intensity, which will produce the deterioration of dynamic extinction ratio, the rise of insertion loss as well as the lessen of switching overall performance.
The Nd:YVO4 crystal is Minimize and oriented in this kind of way that it satisfies the polarization affliction for productive lasing. The Nd:YVO4 crystal can be temperature-stabilized by a thermoelectric cooler (TEC) to take care of its exceptional overall performance.
11a), and one other is to make use of The 2 crystals orthogonally (Fig. 11b, c). The latter is easily the most used technique for many business products, even though our KTP-based EO swap products also make use of this product, as revealed in Fig. 11d, e. Specifically, the same old method of compensating for this is to work with a set of crystals, matched in optical thickness, that's then their applied electric fields orientated at ninety° relative to one another this sort of that light-weight is polarized along the x or y-axis website say in the 1st crystal is then polarized along the z-axis of the 2nd crystal. The “gradual�?ray in the very first crystal then gets the “fast�?ray in the next and the overall static birefringence is Consequently in principle canceled inside the composite crystal pair.
The output beam from your dichroic mirror contains just the green beam, which has a wavelength of 532 nm and an influence of 300 mW. The output beam can be used for a variety of applications which include laser shows, healthcare lasers, or spectroscopy.
Because the wonderful EO properties of KTP had been understood in 1976 along with the obtaining of nonlinear Houses, many endeavours have been created to realize its EO apps, determined by which we recognized the planning of huge dimensions, significant problems resistance, and small conductivity crystals further to fabricate it into EO switches and EO modulators. It is feasible to increase KTP crystals with a complete body weight bigger than ten kg at 1 time (one particular autoclave for every cycle), dependant upon the enhancement of a giant inner diameter autoclave. Through the optimized hydrothermal crystal development process, the electro-chromic, Picture-chromic, and catastrophic laser-induced damages were defeat, and crystals with uniform superior optical, electrical, and piezoelectric Homes had been acquired, creating the business application of HKTP EO crystals a truth.
The dichroic mirror is utilized to independent the infrared beam from the green beam, which can be equally produced inside the cavity. The dichroic mirror reflects the environmentally friendly beam and transmits the infrared beam.
Deploying modern photonic answers built to support tomorrow’s tactical mission prerequisites right now.
Although the linear, nonlinear, and EO Attributes of KTP crystals developed with the flux and hydrothermal approaches are identical, discrepancies have already been observed in certain dielectric Houses and also the extremely high-energy optical hurt traits.
