Abstract

The Matlab application program is often used as a data processing tool as well as tables, 2 or 3 dimensional graphs. Practicum activities for Physics subjects in general, the results of physics experiments are written directly into the experimental report. In practicum activities, the campus tries to make or design a Matlab application program for practicum activities. The results are processed using a computer application program, before being recorded in the report. The Matlab application program is often used as a tool for processing data and tables, 2 and 3-dimensional graphs. Students are given experimental data on Physics about this Matlab program, then analyzed and presented in graphical form and others. The result was that after being given additional lessons in the Matlab program, students processed the results of the physics experiment, and found out if there were experimental data that needed to be improved. Equipped with a tutor textbook. Keywords: Matlab, Physics Experiment, 2D 3D graphics.

Abstract

So far, the transfer of electric power is done by wire or cable. Recent discoveries use electromagnetic waves or magnetic induction. In this study, we tried the latest innovations, namely trials to prove with light as a substitute for wire media. The light (beam) used is a laser beam. The use of a diode type laser optical component with a blue color in the technology for wireless transfer of electrical energy. Laser tested 1500 milliWatt power. The working voltage is 6 Volts, 1 ampere. While the measurement of voltage, current and light strength with a multimeter fluxmeter. The electrical load used for this experiment is a red LED (Light Emiting Diode), with an additional 220 ohm resistor, 0.5 watts.This research method uses the type of experiment (experiment).The variables tested and measured are voltage in volts, current in amperes and light intensity in lux. The power supply can be varied from 0 volts to 15 volts, the current is 1.5 amperes of direct current. Light measuring instrument (fluxmeter or lightmeter) is expressed in lux.The results of the tests and measurements are expressed in the form of a graph of the current voltage and light intensity in the form of a graph. At a distance of 3 meters with a source voltage of 6 volts and 1 ampere on the laser, the electrical energy generated is transferred is an electric voltage of 3.9 volts, an electric current of 8.75 milli-Amperes.From this experiment, it can be proven that light can be used as a medium to distribute or transfer electrical energy, from one place to another, which is called optical wireless energy transfer. The transfer of electric power can be done with light.Keywords: Optical Wireless Energy Transfer, Blue Laser-Diode, Lux.

Abstract

The concept and theory of lasers was first put forward by Albert Einstein in 1917 and was first realized by researcher Theodore. H. Maiman in 1960. The invention of the laser is based on the theories of quantum physics, but research on the properties and optical characteristics of lasers, especially diode lasers is rarely carried out, so references for developing and applying them are very difficult to obtain. Lasers have coherent properties, which are parallel, massive, single-color (monochromatic) light propagations, which are different from incandescent white (polychromatic) light which is commonly known everyday from the sun, fire, lamps and so on. Laser diode devices have various types of power, which of course differ in the amount of voltage, current, strength of light in each condition (Uiga. E, 2014).The purpose of this research is to examine the physical characteristics of the diode laser, to determine the range of the current-voltage limits and the divergence angle in the radiant, to determine the characteristics of the laser diode with different powers.The research method used is experimental, which is carried out by testing variables and measuring the magnitude of the voltage, current, divergence of different powers from the diode laser.Based on the experimental results, the diode laser has a characteristic phase of the Volt-Ampere change called the laser phase. There are 3 phases that have been proven, namely the spontaneous emission phase, the transition phase, the stimulated emission phase and one characteristic that has been found, namely the power characteristics, the strong light (flux) (Uiga. E, 2014 ). The resulting data and variables can be used as a reference, study for research so that they can be used as a basis for further research.Keywords: Laser-Diode, Divergence, voltage, current, power
