Ultraviolet Laser Microprocessing
Ultraviolet (UV) lasers are employed in a broad range of microprocessing applications including in scribing and dicing semiconductor devices, micro-via drilling printed circuit boards and flexible circuits, manufacturing solar cells and in glass machining. UV lasers are also used in the manufacturing process for organic light emitting diodes (OLED) which are increasingly finding their way into consumer electronics, including in smart phones and monitors. Typically, UV lasers are diode pumped solid state lasers for which the wavelength is converted in one or two steps using appropriate non-linear crystals such as LBO or BBO. II-VI’s broad portfolio of products for UV DPSS lasers includes non-linear crystals, laser cavity optics and acousto-optic Q-switching. II-VI also offers products for UV beam delivery systems, including F-theta scan lenses, scan mirrors, focusing lenses and beam expanders.
