    Developments in the field of the stage is now increasingly widespread. More and more people are willing to spend big money to get the quality of a spectacular event., the supplier and the expert in this field is still relatively very little. Lasika now present in Surabaya as one of the oldest home industry to explore the aspect of sound system, rigging, LED, and others. Lasika quality has proven capable and became the mainstay of the city of Surabaya when there are events that bring national artists. To that end, Lasika feel the need to balance between performance and branding is also good for the entire society Surabaya, Indonesia even be able to know the quality offered by Lasika.In this thesis begins, the process of website creation of designs using the use case and the flow chart followed by the creation of websites using Hypertext Preprocessor (PHP) as a programming language and MySQL for its database. Features that will be created that is google calendar, instagram, suggestion, and live chat.Results of the implementation and testing of the website is generating features member profiles, view instagram hashtag, google calendar, suggestion, live chat, and be able to see the products offered by Lasika

    Optimizing Switching of Non-linear Properties with Hyperbolic Metamaterials

    Hyperbolic metamaterials have been demonstrated to have special potential in their linear response, but the extent of their non-linear response has not been extensively modeled or measured. In this work, novel non-linear behavior of an ITO/SiO2 layered hyperbolic metamaterial is modeled and experimentally confirmed, specifically a change in the sign of the non-linear absorption with intensity. This behavior is tunable and can be achieved with a simple one-dimensional layered design. Fabrication was performed with physical vapor deposition, and measurements were conducted using the Z-scan technique. Potential applications include tunable optical switches, optical limiters, and tunable components of laser sources

    Dual-arm Z-scan Technique to Extract Dilute Solute Nonlinearities from Solution Measurements

    Get PDF
    We present a technique in which small solute nonlinearities may be extracted from large solvent signals by performing simultaneous Z-scans on two samples (solvent and solution). By using a dual-arm Z-scan apparatus with identical arms, fitting error in determining the solute nonlinearity is reduced because the irradiance fluctuations are correlated for both the solvent and solution measurements. To verify the sensitivity of this technique, the dispersion of nonlinear refraction of a squaraine molecule is measured. Utilizing this technique allows for the effects of the solvent n2 to be effectively eliminated, thus overcoming a longstanding problem in nonlinear optical characterization of organic dyes

    Temporal, Spectral, and Polarization Dependence of the Nonlinear Optical Response of Carbon Disulfide

    Carbon disulfide is the most popular material for applications of nonlinear optical (NLO) liquids, and is frequently used as a reference standard for NLO measurements. Although it has been the subject of many investigations, determination of the third-order optical nonlinearity of CS2 has been incomplete. This is in part because of several strong mechanisms for nonlinear refraction (NLR), leading to a complex pulse width dependence. We expand upon the recently developed beam deflection technique, which we apply, along with degenerate four-wave mixing and Z-scan, to quantitatively characterize (in detail) the NLO response of CS2, over a broad temporal range, spanning 6 orders of magnitude (∼32 fs to 17 ns). The third-order response function, consisting of both nearly instantaneous bound-electronic and noninstantaneous nuclear contributions, along with the polarization and wavelength dependence from 390 to 1550 nm, is extracted from these measurements. This paper provides a self-consistent, quantitative picture of the third-order NLO response of liquid CS2, establishing it as an accurate reference material over this broad temporal and spectral range. These results allow prediction of the outcome of any NLR experiment on CS2

    Background In recent years, positron emission tomography (PET)-adapted protocols and new agents such as brentuximab vedotin are increasingly used as part of first-line protocols of advanced-stage Hodgkin lymphoma (HL). Objectives This manuscript reviews guideline-based therapy and available trial data in advanced-stage HL. Materials and methods This is a narrative review. Results The German HL guideline recommends interim PET2-guided (PET after 2 cycles) chemotherapy using 4 cycles of eBEACOPP (bleomycin, etoposide, doxorubicin, cyclophosphamide, vincristine, procarbazine and prednisone) for PET2-negative patients up to 60 years of age with advanced HL and 6 cycles eBEACOPP for PET2-positive patients. Furthermore, patients with PET-positive residual lymphoma should receive consolidation radiotherapy with 30 Gy. This is based on effective tumor control and short duration of therapy of 3 months in most patients. For elderly patients, treatment with 2 cycles of ABVD (adriamycin, bleomycin, vinblastine and dacarbazine) followed by 4 cycles of AVD and irradiation of PET-positive residuals is recommended. Conclusions Advanced-stage HL is curable in more than 90% of cases. The goal of current scientific efforts is to reduce toxicity while maintaining efficacy by including immune checkpoint inhibitors

    Microwave antenna properties of an optically triggered superconducting ring

    We examine the microwave radiation emitted from inductively charged centimeter-scale YBCO (YBa2Cu3O7-δ) annular rings illuminated with a 45 fs, 790 nm laser pulse. The electromagnetic radiation from the rings shows the following behavior. (1) Radiation emitted perpendicular to the plane of the ring is polarized parallel to the plane of the ring and across the point of illumination. (2) The in-plane radiation pattern resembles that of a loop antenna with the orientation of the pattern determined by the location of the illumination point. (3) The dominant frequency of the emitted radiation shows an inverse dependence on the ring diameter. (4) The emitted energy is proportional to energy stored in the ring for a number of different geometries, with thinner films displaying a higher efficiency. Finally, (5) the emitted energy grows exponentially with small laser pulse energy values and approaches saturation for higher energies. These results indicate that optically induced electromagnetic radiation from superconducting structures holds promise for a versatile, compact, self-contained superconducting microwave emitter platform
