If you do not find the acceptable products and solutions earlier mentioned, it's possible you'll let us know your prerequisites or purposes in the shape under. Our profits or technological workers will get again for you right away.
The latter include things like Nd:YAG as well as other neodymium-doped lasers. (Contact us to request distinct knowledge on our KTP to view if it is right for the application.)
Extremely top quality KTP has a mix of appealing properties: high damage threshold, significant nonlinear coefficients, huge acceptance angle, and high conversion effectiveness nearly about sixty%.
See how we're powering manufacturing results on the globe's most impressive marketplaces �?from semiconductors to EVs.
“New�?electro-optical (EO) crystals are hard to find, “old�?EO crystals are scarce and every has its have challenges, and also the desire for prime-effectiveness EO crystals by increased electrical power, larger repetition charge, and narrower pulse width laser is reasonable and urgent. The EO performance of KTP was identified the moment it was found, but just after a lot more than forty decades of progress, the stories, and items of EO products according to KTP are a lot less than People of other EO crystals, even though KTP is now Practically the cheapest nonlinear optical crystal substance. In this paper, based on our understanding of the crystal structure of predecessors and ourselves, Specially the understanding and apply of quasi-one particular-dimensional ionic conduction mechanism, we feel that crystal development is An important rationale that has an effect on the controllability of crystal effectiveness.
coating for KTP crystal is very important to reduce the reflection losses and increase the transmission performance with the crystal. The type of coating is determined by the application as well as the wavelength with the laser.
The output coupler is an optical ingredient that partially demonstrates and partially transmits gentle. The output coupler is utilized to kind a resonant cavity Using the Nd:YVO4 crystal, which reinforces the stimulated emission course of action and boosts the output energy. The output coupler also will allow a number of the light-weight to exit the cavity as the output beam.

The products necessary by this technique is comparatively very simple, the cost is reduced, as well as KTP molten salt growth process is experienced, which often can satisfy the applying demands of low-cost, batch, and substantial-regularity KTP frequency conversion equipment. The KTP crystal grown from the hydrothermal process can satisfy the laser frequency conversion demands of greater Electricity density as opposed to molten salt process KTP. At the same time features a decreased resistivity, which is beneficial to electro-optical purposes.
It is generally thought that the Actual physical Qualities of H-KTP experience like a byproduct of its growth approach.
KTP will be the check here mostly applied product for frequency doubling of Nd:YAG lasers and other Nd-doped lasers, especially with the lower or medium electricity density. The following desk lists the key NLO Qualities of KTP for frequency-doubling of the Nd:YAG laser.
When the KTP crystal is utilized as an EO modulator, the used electric powered subject is parallel on the z-axis, and the light propagation direction is parallel to your y-axis or x-axis. If a relatively reduce turn-off voltage is wished-for, a y-axis change is required. In exercise, extended x-axis switches are frequently used to acquire the desired very low flip-off voltage for crystal growth economics. The E-O coefficient with the H-KTP crystal could be decided as adhere to in Desk three. Our EO coefficient measurement benefits at 632.eight nm are in step with the 1986 test results using the hydrothermal strategy KTP32.
The horizontal axis is definitely the calendar year, plus the vertical axis could be the internal diameter in the autoclave. The dimensions from the crystal is essentially determined by the inner diameter of your autoclave, so it can be shown with each other in the graph, marked that has a strong image to differentiate it through the hollow image representing the interior diameter from the autoclave.
The green laser radiation that KTP creates has numerous programs. Eco-friendly laser light has good penetration through ocean h2o, so it truly is utilized for interaction and bathymetric measurement of the sea ground and riverbed characteristics.
