If you don't find the appropriate solutions above, you might allow us to know your requirements or programs in the shape underneath. Our sales or complex staff will get again to you personally immediately.
The latter include things like Nd:YAG as well as other neodymium-doped lasers. (Call us to ask for precise data on our KTP to determine if it is true to your software.)
Hydrothermal approach is the process of crystal advancement underneath hydrothermal circumstances occurs at large regimes and pressures. For that reason, this process potential customers in Unique thick-walled vessels �?autoclaves, manufactured from Specific superior-toughness corrosion and warmth-resistant steel.
Seen by 3608 Summary Scientific studies of polarization reversal processes in potassium titanyl phosphate (KTiOPO4, KTP) single crystals with floor dielectric layer are very important due to their possible apps as the basis of bottom-up technological innovation for generation of periodically poled nonlinear-optical crystals. We existing the outcomes [...] Read far more. Experiments of polarization reversal processes in potassium titanyl phosphate (KTiOPO4, KTP) single crystals with surface dielectric layer are essential due to their possible purposes as The premise of base-up know-how for generation of periodically poled nonlinear-optical crystals. We current the outcome of switching currents Investigation accompanied by in situ visualization of area kinetics throughout polarization reversal in KTP with three m-thick photoresist dielectric layer. Qualitative transform from the switching existing shape has become discovered as compared with the polarization reversal devoid of area dielectric layer.
Experts and engineers dealing with crystals of KTP family members are invited to contribute to The problem.

For commonly paired KTP EO devices, due to sizeable thermo-optic coefficient of your KTP crystal, and the different Strength in the oscillating laser and pumping mild absorbed by the back and front crystals, the thermal depolarization result will come about beneath the problem of superior pumping depth, that can result in the deterioration of dynamic extinction ratio, the increase of insertion decline along with the lessen of switching functionality.
Supersaturation occurs, and crystals start to increase because the temperature is slowly lessened. The containment chamber is extracted and Minimize open up. If all has gone very well, and with a little bit of luck, oriented KTP crystals have developed outward from either side of the seeds.
All through the previous couple of decades, potassium titanyl phosphate (KTP) and its isomorphs have attracted quite a lot of awareness, primarily due to their application in many varieties of photonic devices. These resources possess big nonlinear optic and electro-optic coefficients, high optical problems threshold, and broad thermal and angular acceptance for next harmonic generation.
It's Employed in surgical lasers, wherever selective absorption enables health-related ablation though avoiding harm to adjacent tissue. A lot more precisely, the green gentle made by KTP is utilized for executing some types of prostate surgeries.
KTP may be the mostly made use of materials for frequency doubling of Nd:YAG lasers and also other Nd-doped lasers, notably within the small or medium ability density. The subsequent table lists the main NLO Homes of KTP for frequency-doubling of a Nd:YAG laser.
Ahead of rising crystals by hydrothermal method, the next four jobs need to be accomplished 1st: measuring the solubility (distinct temperatures, unique methods, and distinct pressures); pick out acceptable temperature and temperature distinction; find an autoclave to satisfy the crystal growth necessities; determine the presence and kind of liner according to the problem
When operated in a very thermally compensated method, excellent Q-switching Homes are shown with KTP crystals in a thermally compensated mode30. Salvestrini et al. have a comparative review of five nonlinear optical crystals for EO Q-switching of laser resonators. KTP reveals the best values with the EO software’s merit figures, such as driving voltage, switching speed, and piezoelectric ringing (For every)77. Sadly, due to the relatively large conductivity, when F-KTP was applied as being a high common electricity EO change, electrons injected with the anode in the crystal can reduce the stoichiometric Ti4+ ions from the crystal lattice to Ti3+, regardless of whether File-KTP developed at temperature consistent is employed rather than regular the temperature drop flux method78. On making use of An electrical subject, a black absorbing band moves with the anode in direction of the cathode from the F-KTP, compromising its utility being a Q-switch. This phenomenon will be the electro-chromic destruction described above.
Although the linear, nonlinear, and EO Qualities of KTP crystals grown through the flux and hydrothermal strategies are comparable, variances are observed in a few dielectric Homes and the extremely high-ability optical injury features.
