TECHNOLOGY

BRaMMS DPSS Laser technology by UniKLasers is the company’s proprietary pioneering technology platform.

 

It utilises the spectrum discriminatory feature of a Michelson interferometer setup within a spectral range preselected by VBG (Volume Bragg Grating).  This suppresses all but one lasing longitudinal mode within a laser cavity.  Hence – Bragg Range Michelson Mode Selector (BRaMMS).

Due to significantly lower power consumption for any required output and the resulting simplified thermal management, the BRaMMS laser technology provides up to 10 times wider range of output power scalability from the smallest footprint.

 

UniKLasers advances this technology via three main engineering lines:

 

1.           BRaMMS – Solo:

covering spectrum range 700nm-2000nm by the generation at the fundamental wavelength;

2.           BRaMMS – Duetto:

covering spectrum range 350nm -780nm by an intracavity second harmonic generation;

3.           BRaMMS – Quartetto:

covering spectrum range 200nm – 380nm by an intracavity fourth harmonic generation.

 

BRaMMS Laser Technology  provides new wavelengths

previously unattainable

by DPSS lasers in UV, Visible and Near IR.

The BRaMMS laser technology is wordwide protected by:

  • US 8,498,316 –  Intra-Cavity Second Harmonic Generation (SHG) Laser Device
  • EPO 2424051 –  Intra-Cavity Second Harmonic Generation (SHG) Laser Device

 

Our technology is able to displace bulky and inefficient gas lasers like argon-ion or helium cadmium lasers, dinosaurs of the laser industry. UniKLasers Single Frequency DPSS lasers are compact, reliable and long life systems, in demand for many cutting edge research and industrial applications, for example:

  • life sciences instrumentation,
  • semiconductor wafer metrology,
  • holographic imaging,
  • particle trapping,
  • wind turbine power generation,
  • avionic technologies…
