07 Jul 2008 Diode-pumped frequency-multiplied solid state UV lasers of DPSS Lasers Inc. are available. The laser modules of 35XX series provides an output power of up to 3 W at 355 nm with a repetition rate of 30 kHz. UV lasers can mark plastic materials, as typically used in medical technologies, via a photochemical or photo-bleaching process. Unlike marking made by NIR or IR lasers, the so called "cold" marking process via an UV laser does not thermally damage the material. The marking becomes therefore a permanent part of the material and remains for the whole life and operating time of devices. |
