Q-smart HE

Q-smart HE are amplified Nd:YAG lasers that can reach up to 2.3 J per pulse while keeping excellent beam quality and stability. Using the field-proven Q-smart technology, they encompass plug and play temperature controlled harmonic generators so that the user can choose between various wavelengths: 1064, 532, 355 and 266 nm (213 on request). The single longitudinal mode option (SLM), for linewidth narrowing, allows the specifications of these lasers to be adapted to the most demanding applications.

Key features :

  • High energy packaged in a small footprint
  • 1064, 532, 355 and 266 nm (213 nm on demand)
  • Excellent beam quality
  • Field-proven Q-smart reliability
  • Plug and play harmonic generators with automatic phase-matching
  • Linewidth: 0.005 cm-1 with SLM option
