Measurement & Analysis Lasers

What are Measurement and Analysis Lasers?

Measurement & Analysis Lasers are specialized laser systems commonly used in the research and biophotonics markets for a wide range of applications. These lasers, typically operating in continuous wave (CW) mode, offer high precision and accuracy in measuring and analyzing various physical and chemical properties of materials. While catering to applications like dynamic light scattering, infrared absorption spectroscopy, laser Doppler velocimetry, DIAL LIDAR, and photoluminescence, Measurement & Analysis Lasers find utility in diverse research fields such as physics, chemistry, atmospheric science, and materials science. They play a crucial role in obtaining precise data, performing detailed analysis, and characterizing materials for a deeper understanding of their properties and behaviors. These lasers serve as indispensable tools for scientists and researchers engaged in a broad spectrum of studies and investigations.

Measurement & Analysis Applications

Dynamic Light Scattering Lasers: Dynamic light scattering is a method for determining the size of particles suspended in a solution. This process utilizes the inherent Brownian motion of particles in solution, by looking at the temporal variations in laser light scattered off of these particles. Dynamic light scattering lasers must have a high quality TEM00 beam profile, narrow linewidth (SLM), and a stabilized wavelength.

DIAL Lasers: Differential absorption lidar (DIAL) is a method which allows for stand-off detection of aerosols and gasses in the atmosphere.  In this application, two different lasers sources are used, one which matches an absorption band of the molecule of interest and one which is slightly outside of that band. Because of the wide variety of deployment methods, DIAL lasers are also varied widely from low powered diodes to high powered fiber lasers (typically CW, SLM, single-mode).

Infrared Absorption Spectroscopy Lasers: Infrared absorption spectroscopy takes advantage of the fact that all covalently bonded molecules have vibrational absorption bands whose energy corresponds to infrared wavelengths with overtones in the near infrared. Depending on the set-up, infrared absorption spectroscopy lasers can either be fixed wavelength or tunable but in either case; they must be wavelength stabilized to assure accurate and repeatable results (typically CW, SLM, single-mode, IR).

Laser Doppler Velocimetry Lasers: Laser Doppler Velocimetry is a method for measuring the velocity of transparent, or semi-transparent fluids.  This process relies on a shift in frequency of the output beam to calculate the speed at which the fluid is moving. Since this change in frequency tends to be relatively small, it is essential that the laser source is highly coherent and stable. For this reason, single-frequency continuous-wave laser sources are ideal (typically CW SLM, single-mode, UV, green, IR).

Photoluminescence Lasers: Photoluminescence is a broad term for exciting light emission from a material utilizing a short-wavelength light source as the excitation source. Photoluminescence lasers are typically laser diodes or ns pulsed DPSS lasers, emitting short wavelengths in the UV or Blue spectral regions, utilized for measuring a semiconductor’s bandgap, for example.
