Applications

Raman spectroscopy, Brillouin scattering, Flow cytometry, Optical manipulation, Interferometry, Semiconductor inspection, Wafer fabrication, Lithography, Confocal microscopy, Biomedical/Bioengineering, Fluorescence, Disc mastering, Optical grating mastering, Diffraction grating mastering, High precision optics, and more.

  • Enhanced intensity stability through compact, closed-loop cooling. Enables portability of the laser system without dependence on a water mains connection.

  • Title 01

    Compact, low-cost system cooling which is integrated into the laser platform. Intelligently controlled to maintain stable wavelength output and intensity.

  • External fiber coupling options available to achieve easier integration. Multimode fibers typically achieve > 95% efficiency, for single-mode fibers it is > 70%.

  • Flexible and easy output power adjustment to conserve system lifetime.

  • AOM configuration to achieve up to 200 kHz modulation on the output intensity.
