We report the simultaneous quasi-phase-matching of all three possible nonlinearities for propagation along the X axis of periodically poled (PP) KTiOPO4 (KTP) for second-harmonic generation of 745 nm pulsed light from 1490 nm subpicosecond pulses in a PPKTP crystal with a 45.65 microm poling period. This confirms the recent Sellmeier fits for KTP by Kato and Takaoka [Appl. Opt. 41, 5040 (2002)]...

Database kependudukan nasional yang memiliki sistem pengamanan atau pengendalian baik dari segi administrasi maupun teknologi informasi menjadi dasar dokumen dikenal dengan E-KTP Elektronik KTP. Ini berfungsi untuk mengidentifikasi warga negara Indonesia menggunakan kartu identitas ini. Pada Februari 2011, Kementerian Dalam Negeri memperkenalkan program KTP E-KTP. Dengan E-KTP, semua keamanan b...

District Integrated Services provides e-KTP Management services. Districts play a roles in providing satisfactionto recipients of management services However, reality there are still many people who not satisfied with the achievement completion time for provided. The purpose this study was to determine Qualityof Administration Bantan District, Bengkalis Regency (E-KTP Study) and inhibiting fact...

Solid electrolytes used in all-solid-state batteries electronically separate the positive and negative electrodes battery only allow carrier ions to pass through. KTiOPO 4 (KTP), a potassium ion-conducting solid electrolyte, was first applied as inner contact layer of an ion-selective electrode (ISE) stabilize membrane potential. Application KTP improved long-term potential stability ISE by sta...

We employ ferroelectrics to study the multipolar scattering in all-dielectric metasurfaces based on KTiOPO4 (KTP) micro-disks for efficient manipulation of electromagnetic waves in the THz spectral region (0.6-1.5 THz). By adjusting the aspect ratio of the disks near the multipolar resonances, we show that the KTP disk array can form a multifunctional metasurface that covers the entire range of...

In the present work, KTP crystals have been grown by spontaneous nucleation technique in flux medium using K6P4O13 flux. 0.4-1 °C/h cooling rates were applied in the spontaneous nucleation process. The presence and amount of impurities has been determined by using XRF. The optical transmission spectra of impure KTP crystals in the UV–visible region are discussed. The transmission cut-off is cle...

The tuning curves, angular and spectral phase-matching widths are calculated for all possible kinds of OPG in the principal planes of biaxial KTP crystal with Nd:YAG laser pumping at 1.064 μ wavelength. The plots presented enable the maximal nonmonochromaticity and radiation divergence to be found for any value of the signal wave and different interaction types. A particular emphasis has been p...

BACKGROUND A variety of modalities are available for the control of recurrent epistaxis in hereditary hemorrhagic telangiectasia (HHT). Laser ablation, in particular potassium-titanyl-phosphate (KTP), has gained popularity as it coagulates the telangiectasia with minimal peripheral tissue injury. Septodermoplasty (SDP) also can be performed in the day surgery setting. Telangiectasia recurred, n...
