Trumpf’s TruMicro 2000 series of pulse lasers for microscopic machining offers a pulse duration of 20 picoseconds with 10 microjoules of pulse energy and a 10-W average output power at high brilliance. With an M2 beam quality of less than 1.3, the lasers are suitable for high-precision separation and structuring applications. Controls monitor each individual picosecond pulse from generation through delivery via the external modulator. Output power and pulse energy are kept at the required levels regardless of external influences, the company says.
The small, lightweight lasers feature control options for integration into manufacturing lines. Variations with infrared or green wavelengths are available for a selection of focusing abilities and absorption properties. The laser can be used for applications such as black marking anodized aluminum. The beam passes through the anodized layer of material and causes the metal to change color, while the surface is unaffected.
