Condition: like new (used), Year of construction: 2022, OEM – laser marker / engraving laser (diode pumped YAG-laser) The laser beam source was used for some time to generate plasma as part of a scientific project. Overall, however, it only has few operation time. Due to the short pulse length, this laser is also very suitable as an engraving laser Laser source of the complete system is a 10 Watt diode-pumped YAG-laser with 1064 nm wavelength. The working area is 100 x 100 mm, up to 300 x 300 mm is available as an option. No external cooling is necessary. Input-voltage: 110...240 VAC / 50 Hz. Applications are laser engraving and material ablation. The control software is installed on a PC, optionally also a Laptop can be used. The language of the software can be choosen (German, English). The laser is prepared for an integration into a ‘higher level system’, but can also be used as a 'stand alone' system. In this case interfaces for Interlock, emergency stop, laser control etc. are available. We are happy to support the customer according to his requirements. Pedspyg N Aepfx Am Tjpw
