Fundamentals of Laser Technology
List of Laser Processes
Lasers are playing an ever-expanding role in material processing, from new product development to high volume manufacturing. For all laser processes, the energy of a laser beam interacts with a material to transform it in some way. Each transformation (or laser process) is controlled by precisely regulating the wavelength, power, duty cycle and repetition rate of the laser beam. These laser processes include the following:
Environmental, Health & Safety Considerations for Plastic Laser Material Processing
Laser-material interactions almost always create gaseous effluent and/or particles. The effluent will include various volatile organic compounds (VOCs) and should be routed to an exterior environment. Alternatively, it may be treated with a filtration system first and then routed to an exterior environment. Plastics that contain chlorine, such as PVC, should never be laser processed. Plastic combustion is inherent to laser processing and may produce flames. Therefore, plastic laser material processing should always be supervised.
