Nd:YAG Flashlamp Pumped Laser Systems

General Information

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

The 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, the lasers can be easily integrated with the customer’s devices.

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

Applications

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