Series 8250 High-Power CW Nd:YAG Lasers


250 Watts to 1000 Watts


The 8250 is a series of high-power CW Nd:YAG lasers with output power capability from 250 Watts up to 1000 Watts. It uses the multiple, in-line optical head design technology to develop beam power in increments of 250 Watts. The basic power element of the series is the Model 8250M.

For all models, laser power is continuously adjustable from front panel controls. A remote control console permits simultaneous control of multi-head power units. Interface circuitry is optionally available for digital or analog control via customer supplied computer or mircoprocessor.

Four Series 8250 lasers are presently available:




While this "cascade" technique is neither new nor unique, Lee Laser has engineered several features that greatly enhance each lasers' stability, reliability and safety:

  • all multi-head optical resonators are supported by a 10-cm thick honeycomb or aluminum-frame base that provides rigid, light weight support.
  • all laser heads are mechanically prealigned with a common beam centerline by use of a HeNe laser, to ensure maximum optical coupling efficiency between each head.
  • an electro-mechanical safety shutter is positioned inside the optical resonator to prevent lasing action altogether when the shutter is closed; this is far safer than a beam block positioned outside of the optical resonator, that only absorbs beam power but does not prevent its generation.
  • each laser head is individually cooled by a separate heat exchanger cooling system to ensure highly precise coolant flow and temperature control of each head; systems that use a single cooling unit are subject to uneven flow rates and YAG rod temperatures, instable beam power output, and unpredictable arc lamp lifetime.
  • small diameter YAG rod contributes to better beam quality.
