Abstract
In this article, the authors describe the use of microcomputer simulated experiments in teaching the multi-channel laser system in an undergraduate course. The simulation described here was carried out by students in the context of a Year 4 undergraduate physics laboratory course on pulse technology. The objective of the course was to give the students experience in computation pulsed electrical circuits and in comparing the computation with experiments. To help students understand the sequence of firing of this multi-channel system, we use microcomputer simulated experiments based on circuit analysis and numerical computation with microcomputers. Firstly, the system of equations is kept simple at the level of Kirchhoff's rules applied to a time-dependent coupled circuit. Secondly, the numerical integration uses the simplest linear approximation. The prediction from the computation of the "prolong sequencing" of five laser channels has been verified experimentally. The results show that the microcomputer simulated experiments provide a powerful tool for a more comprehensive understanding of the multi-channel laser system.
