Ultra-short pulse lasers used for the most demanding medical applications.

Ultra-Short Pulse Laser

The Staccato laser is an ultra-short picosecond laser with 2.4W of power at 1030 nm. This laser features pulse energies greater than 30 µJ, high repetition rates of up to 80 kHz, and pulse durations of 1.5 ps.

The excellent beam quality of this laser (M² <1.3) allows for focusing the beam onto very small areas to reach peak power densities sufficient for virtually any material.

Features & Benefits

  • 1.5 ps pulse duration
  • >30 μJ
  • High beam quality M² < 1.3
  • Superior stability
  • Compact and rugged design
  • Low maintenance
  • Ideal for most demanding medical applications
