Spectroscopy laser, Laser spectroscopy is a versatile diagnostic tool for analytical applications and recent advances in semiconductor laser technology (QCL, DFB, VCSEL) combined with selective and sensitive spectroscopic detection techniques have led to the development of new diagnostic tools for trace gas and isotope analysis.
Laser Raman Spectroscopy, Raman spectroscopy is a useful technique for the identification of a wide range of substances - solids, liquids, and gases.
The most commonly used laser wavelength in Raman spectroscopy is 785 nm which offers low fluorescence whilst retaining relatively high Raman intensity. However, for samples which suffer from large fluorescence backgrounds, such as dyes, a 1064 nm laser may be needed. This laser would generally only be used if the fluorescence is extremely high due to the reduction in Raman intensity and risk of sample damage from a more powerful laser.
Figure 1 shows the difference in Raman intensity between a 638 nm laser and a 785 nm laser using a silicon sample under the same conditions.
