Raman spectroscopy is one of the fastest growing and most diverse applications in all of laser spectroscopy.  As a result, it can be rather challenging at times to sift through the wide-ranging laser options all being marketed for Raman spectroscopy.  In this application note we will tackle one of the most common questions that arise when picking a laser for Raman spectroscopy, “Should I chose a single-spatial mode or multi-spatial mode laser for my application?” 

Single-Mode

• Wavelengths from 633 nm to 1064 nm

• Ultra -Narrow Spectral Linewidth (~100 kHz)

• Stabilized Output Spectrum (< 0.007 nm/0C)

• Gaussian TEM00 Spatial Mode

• Single Mode PM Fiber Coupled or Circularized & Collimated Output Beam

 • SMSR 70 dB w/ laser line filter (40 dB without)

Multi-Mode 

• Wavelengths from 647 nm to 1064 nm

• Upto 600mW output power

• Spectral Bandwidth < 0.15 nm FWHM           (< 0.07 nm available upon request )

• “Ultra-Track” Linear Tracking Photodiode

• Low Power Consumption

• Typical 40 dB SMSR
