Technology

Our engineering platform utilizes the spectrum discriminatory feature of a Michelson interferometer setup within a spectral range preselected by a VBG. This suppresses all but one lasing longitudinal mode within the laser cavity. Due to significantly lower power consumption and simplified thermal management, BRaMMS-based lasers provide improved output power scalability from a remarkably small footprint.

Duetto-349 UV Optional Extras

Water Cooling

For specialized applications that demand minimal perturbance and vibration, we offer a water-cooling solution utilizing a high performance thermo-electric chiller. Should your cooling needs change in the future, the water-cooling loop can simply be disconnected from the pedestal and the laser head may be cooled passively. This option replaces our standard passive cooling pedestal.

Versatile Software Control

If you require greater control and monitoring of your laser’s parameters, consider our PC control interface. Depending on your requirements, users can turn the connected laser on and off, refine output power and monitor performance.

Remote Diagnostic Support

We also offer a remote diagnostics option so our laser engineers can monitor the performance of your laser and make necessary adjustments, without the need for a call-out.
