The KTP crystal is really a nonlinear optical material that could transform the frequency of sunshine. The KTP crystal is Lower and oriented in such a way that it satisfies the stage matching problem for 2nd harmonic era (SHG), which suggests that two photons in the enter beam can Incorporate to provide one particular photon of twice the frequency (or half the wavelength) at 532 nm (inexperienced).
EKSMA Optics employs cookies to supply you with the most effective procuring practical experience. In case you keep on to utilize our services, we will presume which you comply with the usage of such cookies.
Extremely top quality KTP has a mix of desirable properties: significant damage threshold, superior nonlinear coefficients, substantial acceptance angle, and superior conversion effectiveness as much as about 60%.

PDF KTP (Potassium titanyl phosphate) is actually a nonlinear crystal typically Utilized in extracavity configuration when just one pass through the crystal is required.
There's two strategies to attain the goal of minimizing σ33. The very first is to reduce thermal defects, non-stoichiometric defects, and impurity defects by managing the growth ailments and growing “great�?crystals. Yet another way to perform minimal σ33 is always to decrease the “bottleneck�?sizing and raise the ion sizing during the channel by doping other favorable atoms. By understanding the structure, there are two major mechanisms for these doping to change the σ33: just one should be to alter the ion mobility during the “channel,�?and one other should be to change the “bottleneck�?of the channel. Naturally, it also consists of The mix and interaction of the website two mechanisms.
The output coupler can be an optical ingredient that partially displays and partly transmits light. The output coupler is used to sort a resonant cavity Using the Nd:YVO4 crystal, which enhances the stimulated emission procedure and raises the output electricity. The output coupler also makes it possible for some of the light to exit the cavity as the output beam.
The Nd:YVO4 crystal is Slice and oriented in such a way that it satisfies the polarization condition for economical lasing. The Nd:YVO4 crystal is likewise temperature-stabilized by a thermoelectric cooler (TEC) to take care of its exceptional general performance.
The laser diode is a device that emits a laser beam having a wavelength of 808 nm (infrared) and an influence of 2 W. The laser diode is used as being a pump resource with the Nd:YVO4 crystal, which can be a laser acquire medium which will amplify gentle at 1064 nm (infrared).
It is generally thought that the Bodily Qualities of H-KTP go through to be a byproduct of its advancement method.
Better optical inhomogeneity can improve the extinction ratio of EO swap and beam high quality with the laser. They are the requirements inside the programs of KTP. Furthermore, we found some variations with regular know-how in the actual exploration procedure. We have now also observed that static strain depolarization is a dilemma in KTP, not like in DKDP and z-axis LN.
The dichroic mirror is accustomed to individual the infrared beam from your eco-friendly beam, which happen to be the two created inside the cavity. The dichroic mirror displays the environmentally friendly beam and transmits the infrared beam.
The horizontal axis would be the calendar year, and also the vertical axis may be the interior diameter from the autoclave. The dimensions on the crystal is essentially based on the interior diameter of your autoclave, so it's shown alongside one another within the graph, marked that has a solid symbol to tell apart it through the hollow image symbolizing the interior diameter on the autoclave.
Although the linear, nonlinear, and EO properties of KTP crystals grown by the flux and hydrothermal methods are identical, dissimilarities are actually noticed in a few dielectric Qualities and the pretty significant-electric power optical hurt qualities.
