Spectroscopy and Analysis Lasers for Industrial/Manufacturing
What are Spectroscopy and Analysis Lasers?
Spectroscopy & Analysis Lasers refer to specialized laser systems (pulsed or CW) utilized in the research and biophotonics markets for various applications such as laser-induced breakdown spectroscopy (LIBS), nonlinear spectroscopy, and Raman spectroscopy. These lasers are designed to provide precise and controlled light sources for detailed analysis of molecular structures, elemental composition, and material properties. LIBS employs high-energy lasers to generate plasma for elemental analysis, nonlinear spectroscopy techniques explore molecular and material properties using intense laser pulses, and Raman spectroscopy uses laser light to probe molecular vibrations and provide molecular insights. Spectroscopy & Analysis Lasers offer precise wavelength control, high power output, and stability, enabling researchers to gain valuable information in fields such as chemistry, physics, materials science, and biomedical research.
Spectroscopy and Analysis Applications
Laser Induced Breakdown Spectroscopy Lasers: LIBS is an atomic spectroscopy technique where a small portion of the material is ablated by a laser (typically ns pulsed, high pulse energy, single-mode, UV, green, or IR) and the resultant plasma emission plume is analyzed by a spectrometer to determine its atomic structure. LIBS is commonly used in mining, forensics, and scrap metal applications for sorting metals and other samples which can’t be analyzed using molecular techniques.
Nonlinear Spectroscopy Lasers: Non-linear spectroscopy is a broad term covering SRS, CARS, multi-photon fluorescence spectroscopy, and terahertz spectroscopy to name a few. The majority of non-linear spectroscopy lasers are used in microscopy applications, requiring single spatial mode for diffraction limited performance. Due the non-linear nature of these techniques, these lasers must have extremely short pulses and therefore q-switched, and mode-locked lasers are typically preferable (typically ps or fs pulsed, SLM).
Raman Spectroscopy Lasers: (CW & ps or fs pulsed, SLM, single/multimode, 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.
