Nd:YAG Flashlamp Pumped Laser Systems

General Information

NS-series Nd:YAG Q-switched laser systems provide with energies from hundreds of mJ up to 1,5J at 1064nm. Stable, telescopic or VRM resonators are available as standard options.

Systems consist of an industrial grade stabilized aluminum laser head and compact power supply unit integrated with efficient water-to-air cooling.

Thanks to their compact size and misalignment-free design, lasers can be easily integrated into customer’s devices.

Detachable or embedded automatically switched harmonics generators up to fifth are available.

Applications

  • LIDAR
  • Ti:Sa / OPO / Dye Lasers Pumping
  • LIBS / Spectroscopy
  • LIDT
  • LIF
  • Material Ablation
