Duma Optronics, new high power laser beam analyzers product line
M² High Power – 4 kW
M² High Power – 10 kW
A new system for High Power laser measurement on line for both focused and collimated beams, based on the multi-axis knife edge scanning laser beam profiler, according to ISO / CD11 146.
BeamOn U3 High Power
Duma Optronics is proud to launch the first combination of a large scale Beam Profiler (1/1.2 inch) combining USB 3.0 with a dedicated built-in automatic filter wheel.
This new Beam Profiler has a brand new software including accurate power measurements and powerful new algorithms for data analysis.The new system will be offered in two basic architertures: One with 40 fps and the second up to 150 fps.
The high pixel density allows flexible measurements from small beam to large beam. Furthermore, the calculations are compliant with ISO standard 11146.
PLX Ball Mounted Hollow Retroreflectors
PLX Ball Mounted Hollow Retroreflector products for laser tracking are the most accurate in the industry and can significantly improve the performance of all laser tracking systems.
They are now available in a unique Break-Resistant configuration as well as in a range of sizes and materials for specific applications. All PLX BMRs are equipped with our standard protected silver coating for the highest durability, reflectance and distance.
PLX Ball Mounted Hollow Retroreflectors are compatible with all laser tracking systems.
Now available in 2 centering accuracies: within .0005″ and within .0001″.
PLX BMRs can significantly improve the performance of all laser tracking systems. They are manufactured in three different diameters: 1 1/2″, 7/8″ and 1/2″. Should the optical elements of your BMR ever become damaged, PLX can replace them with units of comparable accuracy and alignment to the original at a modest cost.

Barium and Strontium Tungstate-Molybdate Crystals
New nominally pure and neodymium doped Barium tungstate, Strontium tungstate and Strontium molybdate single crystals are now available:
New Barium and Strontium tungstate-molybdate single crystals feature higher Raman gain as compared to KGW or CaCO3 and relatively higher thermal conductivity as compared to a Ba(NO3)2.
Barium and Strontium tungstate-molybdate single crystals are grown and provided with cut along a-direction. Active elements do not require precise positioning since stimulated Raman scattering (SRS) threshold slightly depends on the crystal orientation relative to pump polarization (within a few percent) and minimum threshold is reached at E||c. In this case, the polarization of the pump and stokes pulses are parallel to the optical axis (c-axis).
The crystals are water-insoluble and durable. Available sizes and shapes of active elements are rectangular up to 10 x 10 x 100 mm or with cylindrical cross-section up to dia 10 x 100 mm.
Other Choices for Stimulated Raman Scattering
Thermal effects are significantly smaller in KGW. This along with the high damage threshold make the crystal an excellent candidate for power scaling.
Barium Nitrate Crystals
Ba(NO3)2 has the highest Raman gain coefficient among other SRS crystals. However, the thermal lensing is particularly strong in this material.
Bare Fiber Adaptors with Magnetic or Spring Clamp
Bare fiber adaptors provide a simple and effective way to use unterminated fibers with commercial receptacles.
We look forward to supplying you with all the material and information you need and answering any question.
