Picomaster series ultrafast micromachining workstation design

A Class 1 laser-safe enclosure conceals:

Positioning system
Positioning axes are supported by a rigid vibrationisolated granite platform. Mechanical robustness ensures high positioning accuracy at high speed and for high fabrication volumes. Once a galvo-scanner is added, the processing speed in 2D rises to extreme values, whereas the rotary and tilt axes transform the workstation into a truly 3D tool.

Laser choice

• PL10100 with CW diode pumped regenerative amplifier – a good balance between pulse repetition rate and pulse energy
• PL11M with cavity-dumped oscillator – MHz pulse repetition rate
• FOXTROT with pulsed-diode-pumped amplifier – the highest pulse energy
• 1064, 532 and/or 355 nm wavelength, adjustable to material/process
• Integrated pulse and energy control providing flexible pulse-on-demand and burst mode operation, as well as fluence manipulation.

Optics

Advanced beam delivery scheme and cleverly designed focusing optics couple to precisely deliver the laser energy to the target spot intended. Wide range of laser fluences is available for the laser machining process.

Software

• Real-time operation in MS Windows environment
• Synchronized control of positioning and laser subsystems
• Possibility to integrate additional process-specific devices
• Compatibility with CAD and graphic file formats

Advanced software provides full automatic control of all system units. Intuitive and easy at use, it makes the system either flexibly adaptive or process specific. To speed the work up, two different kinds of parameters can be saved into separate files, namely: system parameters (such as speed of positioning

stages, laser pulse repetition rate etc.) apart from those related to processing „geometry“ (size, depth, arrangement etc.). Remote control and fast support via internet is foreseen.

Options

• Vacuum chuck and workpiece fixture
• Rotary and tilt/dwell axes for increased performance
• Vision control with CCD camera
