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

Abstract

Technology helps users do various things and activities that can produce the latest and innovative technology in various fields, including education. MTs Ma'arif Tembarak is a formal secondary level educational institution under the Ministry of Religion in Temanggung Regency. In carrying out archive management still using conventional methods and has not digitized archives, with 1,500 archive data recorded over 3 years. This causes uncertainty in archival documents and the history of follow-up to managed documents as well as difficulty in searching for data and documents. This research aims to design and build a web-based e-archive system for educational institutions to provide solutions to the problems faced. The method in this research uses the waterfall method with system visualization using DFD and ERD in the database management illustration used. The e-archive system was developed on a web basis with PHP and MySQL programming languages using the CodeIgniter framework and tested using the black box testing method with valid results. Next, a user evaluation was carried out on 5 respondents according to user level with the results of the feasibility percentage being 72%, based on the Likert scale, it was said that the impact or use value was good.
