Double-pulse Laser Systems for PIV and LIBS

General Information

Some applications like Particle Imaging Velocimetry (PIV) or Laser Induced Break-down Spectroscopy (LIBS) require nanosecond range double pulse output laser sources with a precise delay between pulses. We offer several solutions from ultra-compact DPSS systems to high-energy flashlamp pumped ones.

All systems provide a minimal temporal step down to 4 ns (in internal synchronization mode) with jitter in the range of +/-0,5ns.

Highly homogeneous beam profiles are available at 1064 / 532nm in base modifications and in a UV range of 355 or 266nm for some models.

Applications

  • PIV
  • 3D PIV
  • LIBS
