Laser Combiner-Nordic Combiner Laser Engine from CrystaLaser

Nordic Combiner - Multi-color Laser Combiner

Combine 4 lasers to 1 Single fiber output 40+ wavelengths High stability and efficiency Multiple colors Compact combiner

  • CrystaLaser has one of the largest wavelength selections of lasers in the industry. CrystaLaser designs and manufactures compact and stable Nordic combiner, which combines multiple color, multiple wavelength lasers into a single beam output. The laser beam will be in the same direction and overlapped together and output from the same aperture.
  • The Nordic Combiner can combine the diode laser systems and the DPSS laser systems together into one beam or one fiber output, enable flexible OEM integration. Up to four lasers selected from our wide wavelength range of laser products can be combined in the compact Nordic Combiner.
  • The combined multiple color laser beam can be coupled into a single fiber which can be a multimode fiber, a single mode fiber, or a polarization maintained fiber; and the output end of the single mode fiber or PM fiber can be optional installed a laser beam collimator to get a collimated laser output with a beam size of around 0.8mm or other beam size according to customer's requirement.


    • Combine up to four different colors of the laser beams into one beam with option of one fiber coupled output or free space output.
    • Each lasers can be individually control on/off by TTL signal up to 20 MHz. High speed digital modulation allows for fast switching of laser wavelengths in arbitrary patterns for complex experiments;
    • Analog control option is available to control each laser's output power level.
    • Our proprietary thermal management technology allows the Nordic combiner to be stable output for the multiple lasers and with low power consumption in a compact housing. Single mode fiber coupled system can reach a stable output within 2% over 24 hour
    • For your special requirements of combining multiple wavelengths from UV visible to infrared lasers, please contact CrystaLaser directly.


    The Nordic combiner laser engine is suitable for the applications that need lasers with multiple colors in biophotonics (microscopy, cytometry, DNA sequencing etc.) and metrology (scatterometry, ellipsometry), interferometer and holography. These applications require a flexible laser source that provides several wavelengths from one optical fiber.
