Paper Abstract

The main processing objects assembled in this machine are precision workpieces. The entire electro- optical mechanical system possesses high accuracy, high stability, and produces a continuously variable waveform of the laser pulse. These qualities enable extremely difficult processing, such as processing very small pieces of different material. Several new techniques were developed, and some main techniques are described: Waveforms are electronically combined to adjust the laser pulse waveform and pulsewidth. A new positioning system using a micro-light spot to indicate position is designed. The precision of laser voltage is very high. It is measured to 0.01% and the laser intensity stability is 1%. The current-limiting resistance is eliminated in the Xe lamp pre-lighting circuit. This results in high pre-lighting stability and less heat. Some other relatively perfect measures are also taken. Practical use of this machine has proven high processing capability.
