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.

Features

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

Applications

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