What are Sensing, Measurement & Characterization Lasers?
What are Sensing, Measurement & Characterization Lasers?Sensing, Measurement & Characterization Lasers are advanced laser systems (typically CW) designed specifically for a range of applications in fields such as machine vision, particle measurement, gas sensing, Raman spectroscopy, and interferometry. These lasers play a crucial role in providing accurate, high-resolution measurements and detailed characterization of various materials and phenomena. They provide researchers, engineers, and scientists with powerful tools to explore, measure, and understand the physical and chemical properties of materials, substances, and phenomena. Their versatility, accuracy, and non-invasive nature make them indispensable in a wide range of scientific, industrial, and research applications.

Sensing, Measurement & Characterization Applications
Interferometry Lasers: Interferometers are optical devices that utilize the interference of superimposed electromagnetic waves to extract information about the test target. Interferometry lasers (typically CW, SLM, single-mode, UV, violet, blue, green, yellow, red) are used in interferometric applications, exhibiting long coherence length characteristics, which are necessary for accurate measurements.
Machine Vision Lasers: Machine vision refers to the process of utilizing active imaging technologies to automate inspection and analysis for process control and robot guidance in industrial applications. Machine Vision Laser sources (typically CW, visible or IR) provide a means for data collection and analysis, feedback for automatic or manual adjustments, or simply throwing a warning light or even stopping the system.
Particle Measurement Lasers: Particle measurement is widely deployed as a means for counting and sizing the number of particles in both air and fluids in optical particle counting and dynamic light scattering applications for example. These lasers (typically CW or ns pulsed, IR) must then have a high-quality continuous-wave TEM00 laser. Otherwise, the speckle pattern of the multi-mode beam will interfere with the measurement of the scattered light.
Raman Spectroscopy Lasers: (CW & ps or fs pulsed, SLM, single/multimod, UV, violet, blue, green, yellow, red) Raman Spectroscopy is an analytical technique, studying the vibrational modes of molecules, used to identify and quantify the chemical composition and molecular bond structure of a sample by the analysis of scattered light. Raman spectroscopy lasers are typically wavelength stabilized VBG laser diodes or single-frequency DPSS lasers, which allows for accurate wavelength shift (Raman shift) measurements, critical to Raman Spectroscopy.
Gas Sensing Lasers: Gas sensing lasers are often distributed feedback lasers (DFB) or distributed Bragg reflector lasers (DBR), widely used as gas sensing lasers (typically diodes, SLM, IR or SWIR) due to their ability to be frequency tuned while maintaining single mode operations. Tunable diode laser spectroscopy (TDLS) can measure the concentration, temperature, and pressure of various gases in-situ under harsh conditions with good time resolution, sensitivity, and selectivity.
