ND-200/400 laser head with power supply unit (19'' format, 3U height) and remote control. ND-200W/400W power supply and cooling unit is twice larger (19'' format, 6U height).




ND-400 is a Q-switched diode-pumped Nd:YAG laser build up on oscillator + amplifier schema. Oscillator includes pump chamber with transverse pumping, linear resonator, electro-optical Q-switch. Then follows the amplifier's pump chamber, also with transverse pumping. Due passive (convective) cooling ND-400 is a maintenance-free device, although its performance is limited with 10Hz repetition rate.

ND-400W is a water cooled modification of ND-400. Water cooling increases the performance up to considerable 100Hz thus making the usage in many industrial applications possible.

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 intergration into the customer's systems. By the same reasons power supply and cooling system units are performed in 19'' rack format.
