nanoplus DFB laser technology
nanoplus uses a unique and patented technology for DFB laser manufacturing, applying a lateral metal grating along the ridge waveguide, which is independent of the material system.
Your DFB laser requirement
- Select your QCL laser at any wavelength between 6000 nm and 14000 nm
- Define the wavelength with 0.1 nm precision
- Check the typical specifications below

Tackling Climate Change
nanoplus lasers were onboard the Curiosity Mars Rover in 2012 and on the TROPOMI satellite in 2017. TROPOMI measures pollutants and greenhouse gases, tropospheric O3 and CH4.
