At present, far better cryogenic cooling in the KTP crystal and better pulse energies, increased repetition rate pump lasers, could also make peak electric power will increase by A further 2 orders of magnitude, and frequency boosts of 100–a thousand moments turn out to be feasible. Correspondingly, the laser-induced materials destruction and terahertz absorption of KTP crystals ought to be compensated much more attention.
The latter include things like Nd:YAG together with other neodymium-doped lasers. (Get hold of us to request particular knowledge on our KTP to check out if it is right for your software.)
Extremely top quality KTP has a mix of desirable properties: large problems threshold, substantial nonlinear coefficients, huge acceptance angle, and large conversion effectiveness around about sixty%.
ninety five%. Owing to the big 2nd-buy nonlinear optical coefficient and sufficiently large crystal of KTP, its application is challenging to be replaced within the selection permitted with the wavelength of KTP. At the same time, In the event the HKTP with a lot less loss and higher conversion effectiveness is made use of, it will even Enjoy a role in improving the laser Electrical power of some wavelengths significantly lower compared to 1064 nm laser.
Experts and engineers working with crystals of KTP spouse and children are invited to lead to The difficulty.
Then the temperature is raised to 1300 degrees K to dissolve all the elements being a saturated Remedy. Pursuing that, The full product is gradually cooled to around area temperature.
Submitted papers ought to be properly formatted and use very good English. Authors may possibly use MDPI's English modifying assistance just before publication or in the course of writer revisions.
See how we’re aiding pros and institutions �?from research amenities and OEMs to hospitals and dentists �?obtain better outcomes.
Filters down below or the form at The underside can be used to assist item research or make even more inquiries.
Use the superb problems threshold, harmonic conversion performance, and section-matching number of Borate crystals for frequency multiplication in lasers and amplifiers. Find out more
KTP may be the mostly utilised content for frequency doubling of Nd:YAG lasers and also other Nd-doped lasers, particularly at the low or medium power density. The subsequent desk lists the key NLO properties of KTP for frequency-doubling of the Nd:YAG laser.
When the KTP crystal is made use of as an EO modulator, the utilized electric powered subject is parallel to your z-axis, and the light propagation path is parallel for the y-axis or x-axis. If a comparatively decreased convert-off voltage is wanted, a y-axis switch is needed. In follow, prolonged x-axis switches are sometimes utilized to acquire the specified low transform-off voltage for crystal expansion economics. The E-O coefficient in the H-KTP crystal can be identified as observe in Table three. Our EO coefficient measurement outcomes at 632.8 nm are according to the 1986 check effects utilizing the hydrothermal process KTP32.
The horizontal axis is definitely the 12 months, get more info as well as vertical axis is the interior diameter with the autoclave. The dimensions in the crystal is essentially determined by the interior diameter of your autoclave, so it can be shown jointly while in the graph, marked using a sound symbol to tell apart it from the hollow symbol symbolizing the inner diameter on the autoclave.
Even though the linear, nonlinear, and EO Attributes of KTP crystals grown because of the flux and hydrothermal methods are similar, discrepancies are actually observed in certain dielectric Qualities as well as really superior-electricity optical destruction characteristics.
