If you do not discover the appropriate solutions previously mentioned, you may let's know your demands or applications in the shape below. Our income or specialized team will get again to you personally at the earliest opportunity.
The latter contain Nd:YAG as well as other neodymium-doped lasers. (Get in touch with us to ask for particular information on our KTP to discover if it is correct in your application.)

Comparison of chosen Houses of EO crystals, LN, and KTP, respectively. KTP was preferred for EO devices for high-electricity and superior-repetition rate laser as a result of its decreased absorption, exceptional thermal Homes, and identical EO Attributes. The thermal influence of EO products is very first since KTP is really a quasi-1D superionic conductor, Therefore the electrical conductivity is optimistic dependant upon temperature, resulting in electron-induced harm and discoloration at higher temperatures. Second, accompanying the increase in laser ability, certainly one of the principal troubles was the thermal defection with the again-propagating beam as a result of thermally induced refractive index gradients (thermal lensing impact). Moreover, although the birefringence improve due to the temperature modify may be compensated through the double-crystal composition, the KTP with a substantial thermo-optic coefficient, as well as the oscillating laser and pumping light Electrical power absorbed with the entrance is often compensated plus the again two crystals are distinctive, so in the superior pumping.
Researchers and engineers working with crystals of KTP spouse and children are invited to add to The problem.
There are two methods to attain the intention of lessening σ33. The very first is to lower thermal defects, non-stoichiometric defects, and impurity defects by controlling The expansion conditions and rising “great�?crystals. Yet another way to accomplish reduced σ33 is usually to lessen the “bottleneck�?dimension and raise the ion dimensions during the channel by doping other favorable atoms. By understanding the composition, There's two most important mechanisms for these doping to alter the σ33: one will be to alter the ion mobility during the “channel,�?and the opposite is always to change the “bottleneck�?on the channel. Not surprisingly, Additionally, it consists of The mixture and conversation of The 2 mechanisms.
For commonly paired KTP EO equipment, mainly because of the sizeable thermo-optic coefficient of your KTP crystal, and different Electrical power from the oscillating laser and pumping light-weight absorbed by the front and back crystals, the thermal depolarization influence will come about underneath the problem of large pumping depth, that will result in the deterioration of dynamic extinction ratio, the increase of insertion decline as well as the reduce more info of switching efficiency.
The collimating lens is surely an optical element that converts the diverging beam from your laser diode right into a parallel beam. The collimating lens is utilized to Enhance the beam quality and lessen the beam divergence.
The equipment required by this technique is relatively very simple, the expense is low, along with the KTP molten salt growth course of action is mature, which may meet the appliance needs of low-Value, batch, and high-regularity KTP frequency conversion devices. The KTP crystal grown via the hydrothermal approach can fulfill the laser frequency conversion needs of bigger Electricity density compared to the molten salt strategy KTP. Simultaneously contains a lower resistivity, which is beneficial to electro-optical programs.
It is usually thought that the Bodily Qualities of H-KTP suffer as a byproduct of its progress approach.
A KTP crystal can be employed for different applications like laser operation, pores and skin treatment plans, laser tips, RGB displays, and tunable sources for that obvious to mid-infrared array. It can even be useful for electro-optic units including Q-switches and modulators
This Special Situation will cover an array of subject areas associated with KTP crystals: from previous achievements in crystal development, enhancement of The grey-track resistance, and examine in their piezoelectric, ferroelectric, electrooptical, and nonlinear-optical properties to numerous photonic applications in broad spectral vary from near UV to THz.
Deploying innovative photonic methods meant to guidance tomorrow’s tactical mission demands right now.
The inexperienced laser radiation that KTP produces has quite a few applications. Inexperienced laser light has fantastic penetration by means of ocean h2o, so it really is utilized for interaction and bathymetric measurement of The ocean floor and riverbed options.
