Title:
UV LASERS AND UV RAMAN SYSTEMS FOR EFFECTIVE AND EFFICIENT MOLECULAR SPECIES IDENTIFICATION WITH RAMAN SPECTROSCOPY
Document Type and Number:
WIPO Patent Application WO/2019/221770
Kind Code:
A3
Abstract:
The present invention relates to a novel stand-off distance chemical detector system such as can be used, for example, for standoff detection of explosives. Instead of a conventional lasing medium, a Pr:YAG or Pr:BYF based UV laser is used which can be advantageously implemented in Raman spectroscopy.
