ULR Series RF-excited CO2 10-500W Lasers

The ULR series of CO2 lasers for OEM use are based on a sealed, RF pumped, slab design that produces a high-quality beam. These lasers can be operated in CW mode or modulated to control average power. Modulation is accomplished by varying the pulse width of the input signal.

In the 10 W to 500 W lasers, RF electrodes are spaced apart to allow the laser beam to form without influence of the electrodes, delivery excellent near- and far-field quality with minimal wave-guide effects. The folded resonator design allows generation of power in a compact package. Our lasers require no consumables and deliver a very long lifetime.


When you purchase an OEM laser you are not only buying a laser source, but a partnership. That partnership means you receive direct access to world-wide technical support and the shortest service turnaround times, access to the most advanced Applications Laboratory and the most robust and reliable lasers on the market for as long as you own and use the product.

  • Space Saving and Easily Integrated: The patented multi-pass, slab resonator design is the foundation of our robust and highly reliable laser sources. Our integrated air-cooled and internally RF-stimulated lasers eliminate the need for additional space and cost for chillers, and external power sources. Integrating the aser sources into your production or research process is as easy plugging it in.

  • Broad Product Line of Air-cooled Options: We manufacture single resonator air-cooled lasers in power ranging from 10-75 and 250 watts and dual resonator lasers at the 100, 120, 150, and 500 watt range.

Main Difference between UL Series and ULR Series Lasers

The bottom and connector are swallow-tailed and 12PIN respectively but the bottom and connector are flat and 15PIN respectively. There is no difference on performance.

For used Universal lasers, we provide fully-refurbishing services at very low prices. The refurbishing includes replacing optics, RF power supply and refilling gas. All the jobs will be finished within 7 days.

Beam Output Configuration:

With the 90 degree output the beam goes through the base plate. We cut a hole in the bottom and mount it to the face of the laser, turn it 90 degree down through the hole. We can not offer it in any other direction but through the bottom of the base plate. To offer this option on OEM lasers the beam output number is (#3) for 90 degree without pointer, (#4) for the 90 degree with pointer. This option is not offered on 10W Integrated air cooled due to the small base plate and no room to mount the out put.
