Laser platform concept
The initial plartform is made of two lasers with different pulse durations. In order to optimize the cost and the developement time, these are available from the shelves as standard products
One is a nanoseconde laser with a stronger thermal effect on the material. It is used for the metallic substrates like the aluminum.
The other laser is a pico seconde laser that has less thermal effect and therefore with be used on the composite parts in order to avoid to damage the surface when texturing.
Both beam are optically aligned and combined in order to "supply" one ouput beam. Laser can be triggered independently depending on the required material to process.
For the concept the average usefull power is 50 watts. More power (approx 1kw) will be required for the industrial demonstrator version.
