Light Conversion's PHAROS and CARBIDE-CB3 lasers have an option for tunable GHz and MHz burst with burst-in-burst capability – called BiBurst.

In standard mode, a single pulse is emitted at some fixed frequency. In burst mode, the output consists of pulse packets instead of single pulses. Each packet consists of a certain number of equally separated pulses. MHz-Burst contains N pulses with a nanosecond period, GHz-Burst contains P pulses with a picosecond period. If both bursts are used, the equally separated pulse packets contain sub-packets of pulses
(burst-in-burst, BiBurst).

PHAROS and CARBIDE lasers with the BiBurst option bring new capabilities to high-tech manufacturing industries such as consumer electronics, integrated photonic chip manufacturing, future display manufacturing, and quantum technologies.

  • Burst-in-burst capability – BiBurst
  • 1 kHz – 2 MHz carrier frequency
  • 190 fs – 20 ps tunable pulse duration
  • Adjustable intra-burst amplitude slope
  • Adjustable number of pulses in GHz and MHz burst

Applications:

  • Brittle material drilling and cutting
  • Deep engraving
  • Selective ablation
  • Volume modification of transparent materials
  • Hidden marking
  • Surface polishing
  • Surface functionalization
