GHz-mode, intra burst pulse separation ~200 ps*, max no. of pulses 1 .. 25  MHz-mode, intra burst pulse separation ~15 ns*, max no. of pulses 1 .. 9  Would this solution be acceptable?  kHz burst repetition rate and 400 pulses at 10 Watt, the burst  energy will be around 100 uJ and the single pulse energy will be  around 250 nJ. 25 pulses in GHz Burst mode is not sufficient.  Q12  Item 1.5.8 - cutting with tolerances within 0-20 μm range of the targeted value  Cutting tolerances depend on samples material and processing speed: please, specify  what you want to do (micro-machining process) and target for each material.  The laser will be used in a prototyping center to process different  materials. The main application is micro-machining. Engraving,  cutting and structuring are the main aims. The materials are  glass, metal and ceramic. In all of them the tolerances should be  better than 20 μm. For the glass and ceramics, the aim is to not  to need post-processing after the micro-machining, so there  should be no micro-cracks. For the metals, main idea is to not to  have  heat  affected  zone  around  the  drilled  holes  or  micromachined surfaces. A general tolerance of 20 μm is set and  it is mainly driven by the spot size of the laser beam during  micro-machining. It will differ for different materials during  processing. In any case, failures higher than 20 μm is not  acceptable.  Q13  Item 1.5 “High Pulse Laser”  Quote:  “Machine shall be configured for precision processing of workpieces made from  various materials.”  Could you please specify any typical expected feature sizes of proceed workpieces?  The sample size shall be 10 cm x 10 cm x 1mm. Features will  depend on the application, but the feature sizes shall be around  10-20 μm for micromachining. For surface structuring, smaller  features smaller than 5 μm shall be provided (LIPSS for  example).  Please refer to Changes No:1 to the Tender Dossier, article 1.5.1.
