The LPY10J Ultra High Energy Pulsed Q-switched Nd:YAG Lasers with extended capabilities.


The LPY10J laser systems offer 10J Q-switched output energies from a proven design platform. The self-supporting Invar frame has been utilised in industrial and scientific applications where robustness and stability are paramount.

The modular design lends itself to several standard configurations of laser all using the same underlying laser components. An optional seeder can provide a narrow linewidth output. Optional harmonic generation units can provide output up to the 4th harmonic.

Other options available include automated moving mirrors to select different output wavelengths, energy monitoring and automatic output peaking.

Applications include:

  • Ti:Sa Pumping
  • Laser Shock Peening
  • LIBS
  • LIDT
  • Holography
  • Plasma Physics
