ULO Optics’ beam combiners allow coupling a low power visible red laser into a beam path of a high power infrared beam for set-up of the downstream optics. They transmit the high power CO2 beam, and reflect the aiming laser at 45 degrees, overlapping the two beams. Standard components are available for 10.6 μm / 633 or 670 nm. Other wavelength combinations are possible, but note that the ‘reverse beam combiner’ where the long wavelength is reflected and the short wavelength transmitted are not possible. It is possible to simulate the latter by using a normal beam combiner with additional mirrors.
The beam combiners are supplied mounted with a red diode laser in our CO2mpact unit C-BI
R at 633 or 670nm > 99% at 45 degrees
T at 10.6 μm > 99%
ULO Optics is an ISO certified company and quality is at the heart of everything we do. With a host of industrial affiliations you can rely on ULO to deliver.
Beam Expanders for 1μm lasers
ULO Optics are excited to introduce our new range of beamexpanders. Designed for low power (500w) lasers such as Nd:YAG and Yb doped fibre lasers operating near the 1μm wavelength. The beamexpanders are of Galillean design and use Multi-spectral Zinc Sulphide for the optics which has an absorption at 1μm of 0.0005cm−1 (Similar to ZnSe at 10.6μm).
ULO Exhibit in Munich
ULO Optics will exhibiting at this year’s Laser World of Photonics exhibition and would like to invite all existing and potential customers to come and visit our stand.

ULO Optics develops CO2 Brewster plate beamcombiner
In our new beamcombiner – C-BC-2, pairs of enhanced Brewster Windows are used to attenuate a linearly polarised CO2 laser beam. The Brewster plate acts like a polarising beamsplitter. The difference in reflectance also allows two perpendicular polarised beams to be combined into a single beam.
