Inherent material fluorescence is largely suppressed with DUV excitation as many materials encountered in forensic investigations exhibit strong fluorescence when excited with 785 nm, the most commonly used wavelength for portable Raman systems.  To overcome fluorescence, manufacturers are now offering 1,064-nm systems.  DUV excitation provides approximately the same level of fluorescence reduction over 785 nm as 1,064-nm excitation, but at 200 times the signal strength.

DUV Raman has reduced detonation probability of explosives.  It is believed that certain Raman systems using tightly focused 785-nm or 1,064-nm sources can cause deflagration or detonation of explosive materials.  DUV Raman systems have been extensively tested on an array of energetic materials, such as C-4 (RDX), ammonium nitrate/fuel oil (ANFO), and primary explosives (mercury fulminate), and have not experienced a single initiation or detonation.
