Several properties of laser radiation make it an extremely valuable tool for measurement systems. The narrow spectral line-width makes it possible to detect resonant effects with very high accuracy. The spatial coherence allows to use the radiation for interferometric measurements with nanometer accuracy. Its high intensity allows us to make use of the non-linear response of materials, for example by ablation.

cosine has heritage in several of these techniques, such as Laser Imaging Detection And Ranging (LIDAR) to measure the distance to the studied objects so accurately that a 3D image can be construed from it, Laser Induced Breakdown Spectroscopy (LIBS) to determine atomic composition, Raman spectroscopy to determine molecular composition, Laser Interferometery to determine microscopic geometry and Laser Diffraction Pattern Analysis to determine macroscopic geometry.
