If you do not find the ideal products above, chances are you'll let's know your prerequisites or apps in the form underneath. Our income or technological personnel can get again to you at the earliest opportunity.
The latter include Nd:YAG and also other neodymium-doped lasers. (Contact us to ask for unique information on our KTP to check out if it is right for your software.)

“New�?electro-optical (EO) crystals are hard to find, “outdated�?EO crystals are scarce and every has its possess challenges, and the demand from customers for top-performance EO crystals by bigger energy, higher repetition rate, and narrower pulse width laser is realistic and urgent. The EO functionality of KTP was identified when it had been found, but after over 40 several years of enhancement, the reports, and products and solutions of EO products dependant on KTP are below People of other EO crystals, Though KTP is currently Just about The most affordable nonlinear optical crystal content. During this paper, depending on our comprehension of the crystal structure of predecessors and ourselves, Specifically the comprehending and follow of quasi-one particular-dimensional ionic conduction mechanism, we are convinced crystal growth is The most crucial motive that impacts the controllability of crystal effectiveness.
Then the temperature is raised to 1300 levels K to dissolve many of the components as a saturated Option. Subsequent that, The full gadget is bit by bit cooled to around home temperature.
Lasers with slicing-edge functionality and industrial trustworthiness with the pioneer in ultrafast lasers. Get well data speedier and publish a lot more.
The Nd:YVO4 crystal is Reduce and oriented in this kind of way that it satisfies the polarization situation for economical lasing. The Nd:YVO4 crystal is usually temperature-stabilized by a thermoelectric cooler (TEC) to maintain its best performance.
The devices needed by this technique is relatively basic, the price is very low, and also the KTP molten salt advancement approach is experienced, which may satisfy the applying specifications of reduced-Price tag, batch, and significant-regularity KTP frequency conversion products. The KTP crystal developed via the hydrothermal process can fulfill the laser frequency conversion specifications of increased Electrical power density as opposed to molten salt strategy KTP. Concurrently has a decreased resistivity, which is beneficial to electro-optical apps.
It is mostly thought that the physical properties of H-KTP put up with for a byproduct of its advancement method.
A KTP crystal can be utilized for several purposes including laser operation, pores and skin remedies, laser ideas, RGB displays, and tunable sources to the seen to mid-infrared vary. It may also be used for electro-optic gadgets including Q-switches and modulators
Once the KTP crystal is utilised as an EO modulator, the applied electric powered industry is parallel to your z-axis, and The sunshine propagation way is parallel into the y-axis or x-axis. If a comparatively reduced turn-off voltage is wished-for, a y-axis change is required. In exercise, extended x-axis switches are frequently made use of to get the desired very low change-off voltage for crystal growth economics. The E-O coefficient on the H-KTP crystal may be decided as stick to in Desk 3. Our EO coefficient measurement effects at 632.8 nm are per the 1986 test effects using the hydrothermal system KTP32.
Although the adoption of your flux approach for KTP escalating has played a essential role in the practical software of nonlinear optical crystals, especially the popularity of environmentally friendly strong-condition lasers in intake and processes. Furthermore, LiB3O5 (LBO)seventy two and β-BaB2O4 (BBO)73 are commonly applied nonlinear optical crystals developed by flux method. The flux approach has played an irreplaceable position in the material preparing of nonlinear optical crystals. Simultaneously, these a few nonlinear optical crystals, consequently, the flux technique, retains their position as A necessary technique for industrial crystal development. The numerous advantage of the flux approach is crystal expansion is often reached underneath ambient pressure. Nine years once the hydrothermal growth of Rb1−xKxTiOPO4 (one.0 ≥ x ≥�?), RKTP crystal was very first noted, and flux approach are already employed by groups in the two the Soviet Union74 and China75,76. Crystal sizing is not the obstacle to EO gadgets fabricated by F-KTP71. After the flux method grows crystals of sufficient size, the EO properties and EO purposes of File-KTP have also been analyzed.
A number of openings of a certain diameter are reserved to slow down the dopant. It communicates Together with the substances click here in The full process to appreciate the gradual launch of trace amounts of doping. We make reference to this technologies as well as a series of supporting systems, including the micro-doping sustained-launch hydrothermal engineering (MSHT). Following adopting this technology, the σ33 uniformity of your crystal is enhanced, Hence considerably increasing the results charge of EO crystal pairing into EO Q-switches from 50% to about seventy five%.
