Paper Abstract

An A / D acquisition system was developed for an iodine- stabilized He-Ne laser for better characterization of the operating parameters and an automatic frequency locking on the iodine feature was the aim of our experimental work. A dedicated software was developed to enable the automatic acquisition circuitry to locate and lock onto the chosen iodine-peak from the groups d, e, f, g, or h, i, j, by making use of second and third harmonic components of the detected signal. More, a warning signal is sent by the PC AT compatible computer to the electronic controller to acknowledge the lock condition.
