Kecamatan Kampar Kiri Hilir Kabupaten yang merupakan instansi pemerintah melayani masyarakat salah satunya dalam bidang administrasi kependudukan seperti pendaftaran Kartu Tanda Penduduk (KTP) dan Keluarga (KK). Namun saat ini sistem pelayanan dilakukan di Kantor masih secara manual. Karena proses KTP KK rumit sehingga membutuhkan waktu cukup lama. Dengan kemajuan teknologi pesat berpengaruh pa...

We report the observation of beatings of the coincidence event rate in a Hong-Ou-Mandel interference (HOMI) between signal and idler photons from a parametric downconversion (PDC) process inside a multimode KTP waveguide. As an explanation we introduce biphotonic states entangled in their broadband frequency modes generated by waveguide mode triples and propose a suitable entanglement detection...

Two-dimensional quadratic spatial solitons were generated experimentally near phase-matching conditions for type II frequency doubling in KTP by the seeding of a strong second-harmonic field with a weak input at the fundamental wavelength. The self-trapped beams were shown to be insensitive to the energy, phase, and polarization of the fundamental-frequency seed input beam.

We analyze the generation of single spatial mode, spectrally uncorrelated photon pairs via type II spontaneous parametric down-conversion in a Potassium Titanyl Phosphate (KTP) waveguide using real experimental parameters. We show that this source can be used as an efficient, heralded, pure-state single-photon source.

We investigate the different characteristics of the intensity noise of a laser-diode-pumped single-frequency ring Nd:YVO (4) laser and a Nd:YVO (4)-KTP green laser. By use of an optoelectronic feedback circuit connected directly to the pump current of the laser diode, the low-frequency intensity noise of the intracavity frequency doubler was suppressed to some extent.

We generated -2.2 dB of broadband amplitude squeezing at 1064 nm in a periodically poled KTiOPO4 (PPKTP) waveguide by coupling of the fundamental and second-harmonic cw fields. This is the largest amount of squeezing obtained to date in a KTP waveguide, limited by propagation losses. This result paves the way for further improvements by use of lower-loss buried ion-exchanged waveguides.

We demonstrate a 4.6-to-1 modulation depth imposed on the fluence of an intense 1.06-microm picosecond pulse by varying the relative phase of a weak second-harmonic control pulse under near phase-matched conditions. This transistorlike action is based on quadratic nonlinearities in KTP.

Objective: To review the initial experience of potassium-titanyl-phosphate (KTP) laser photoselective vaporization of the prostate (PVP). Materials and methods: Thirty patients with benign prostatic enlargement who underwent PVP at our institution between March 2007 and June 2009 were prospectively analyzed. The efficacy of the procedure was assessed using the International Prostate Symptom Sco...

Falling, and the fear of falling, is a serious health problem among the elderly. It often results in physical and mental injuries that have the potential to severely reduce their mobility, independence and overall quality of life. Nevertheless, the consequences of a fall can be largely diminished by providing fast assistance. These facts have lead to the development of several automatic fall de...

In this work the synthesization process of nanocrstallite Nd:KTP powders by modified Pechini method was studied. The results of XRD studies indicate that KTP nanocrystallites doped by Nd has orthorhombic phase. The structural and lattice modes of the synthesized nanocrystallite products were investigated by using Micro Raman back scattering and FT-IR transmission spectroscopies. SEM imaging tec...
