VGEN-G

HIGH PULSE REPETITION RATE WITH TUNABLE
SHORT PULSE WIDTH FOR FINE MATERIAL PROCESSING

  • Up to 30 W average output power
  • 3–50 ns (preset values) pulse width
  • Single shot to 1500 kHz (tunable) repetition rate
  • Up to 200 µJ pulse energy (typical 170)
  • Air-cooled

Spectra Physics' VGEN-G series of pulsed green fiber lasers (532 nm) incorporate cutting edge technology to provide top performance for such precision-intensive applications as a solar cell, micro machining, silicon scribing, fine processing, thin film cutting and more. The VGEN-G lasers are comprised of short-pulse, linearly polarized Ytterbium fiber lasers in MOPA configuration along with SHG (second harmonic generation) module, providing an output power of up to 30 W.

VGEN-G lasers offer a high pulse repetition rate (up to 1.5 MHz) combined with a very short pulse (tunable down to 3 ns) and high peak power which enable high system throughput for maximum operation efficiency.

Housed in a robust assembly that meets industrial standards and fitted with metal armored fiber cable, the VGEN-G delivers a high quality, near-diffraction-limited output beam.
