Q-switched diode pumped Nd:YAG lasers
ND-150 W – 1064 nm, 150 mJ, 100 Hz

Relatively low energy Nd:YAG lasers with diode pumping.
Rod diameter 5 mm, pulse energy 150 mJ by default (100 mJ -200 mJ on request). 100 Hz pulse repetition rate. Water cooling (with external chiller).

ND-150W from Photonics Laboratories is a very simple Q-switched diode-pumped Nd:YAG laser. Pump chamber with transverse pumping, linear resonator, active Q-switching. Output energy achieves 150 mJ per pulse (100-200 mJ on request), pulse repetition rate is as high as 100 Hz.

ND-150W is a water-cooled solution, so it requires an external chiller. Passively or forced-air cooled modification are available on special request for applications where maintenance-free is important, however their performance will be limited with 10 Hz – 30 Hz repetition rate.

Rigid laser head machined from the single piece of aluminium and spring-free design of mirror holders make ND-series a perfect choice for applications where the reliability is important.

ND-series lasers are equipped both with stand-alone UI (remote control with 7” graphical display and touch panel) and RS-485 machine interface. That allows both laboratory usage and integration into the customer’s systems. By the same reasons power supply and cooling system units are performed in 19” rack format.


  • Compact, but very powerful solution
  • Rugged alignment-free design
  • 2 Year warranty
  • Easy integration with customer’s system
  • Fair prices


  • Pumping (OPO, Ti:Sapphire, Dye laser pumping)
  • Scientific (LIDAR, LIF, LIBS, LIDT)
  • Material processing (laser marking, cleaning)
