  The gold lined containment vessel, an autoclave which may stand up to the high temperature and tension without having contaminating The expansion solution, is welded shut and inserted in the metal cylinder.

Comparison of picked Homes of EO crystals, LN, and KTP, respectively. KTP was most well-liked for EO units for top-electrical power and large-repetition charge laser as a consequence of its decreased absorption, excellent thermal Attributes, and comparable EO Homes. The thermal outcome of EO equipment is very first because KTP is often a quasi-1D superionic conductor, And so the electrical conductivity is good depending on temperature, leading to electron-induced destruction and discoloration at significant temperatures. Second, accompanying the rise in laser power, one among the first difficulties was the thermal defection with the back again-propagating beam as a result of thermally induced refractive index gradients (thermal lensing influence). Moreover, Even though the birefringence transform caused by the temperature alter can be compensated because of the double-crystal framework, the KTP with a sizable thermo-optic coefficient, plus the oscillating laser and pumping gentle Power absorbed by the front is usually compensated along with the back two crystals are distinctive, so while in the high pumping.

PDF KTP (Potassium titanyl phosphate) is actually a nonlinear crystal typically used in extracavity configuration when an individual go through the crystal is needed.

KTP crystal (Potassium Titanyl Phosphate) is an excellent and nevertheless inexpensive non-linear crystal features A variety of KTP Crystal special attributes:

Throughout the last few many years, potassium titanyl phosphate (KTP) and its isomorphs have captivated quite a lot of focus, mainly due to their software in different kinds of photonic devices. These materials have significant nonlinear optic and electro-optic coefficients, superior optical harm threshold, in addition to wide thermal and angular acceptance for 2nd harmonic generation.

Schematic with the principal diagram of the temperature-managed solitary-crystal and d temperature-compensated double-crystal EO switches; b Photograph and c layouts of KTP EO Q-swap; e On the web monitoring device for EO swap pair set up; file Experimental setup for characterization of piezoelectric ringing outcomes (PE); g Pockels cell (PC) to be tested; Waveform diagram from the h KDP Laptop underneath 10 kHz, and KTP Computer system below i ten kHz, j one hundred kHz, k 200 kHz

Improved optical inhomogeneity can Increase the extinction ratio of EO swap and beam quality of the laser. These are generally the demands during the apps of KTP. Moreover, we found some variations with traditional awareness in the actual investigation process. We have now also observed that static strain depolarization is a challenge in KTP, contrary to in DKDP and z-axis LN.

The new interest in raising the frequency conversion effectiveness by periodical poling working with fashionable methods of micro- and nanodomain engineering while in the crystals of KTP household is enormous.
