Abstract

Summary form only given: Volume Bragg gratings in Photo-Thermo-Refractive (PTR) glass enable unmatched filter performance for RAMAN spectroscopy. High diffraction Volume Bragg gratings in Photo-Thermo-Refractive (PTR) glass enable unmatched filter performance for RAMAN spectroscopy. High diffraction efficiency combined with ultra-narrow bandwidth provide simultaneous access to Stokes and anti-Stokes Raman modes with frequencies as low as 5 cm^-1. Recent advances in the technology of the diffractive elements in PTR glass enabled fabrication of Raman filters with optical density OD>5.efficiency combined with ultra-narrow bandwidth provide simultaneous access to Stokes and anti-Stokes Raman modes with frequencies as low as 5 cm^-1. Recent advances in the technology of the diffractive elements in PTR glass enabled fabrication of Raman filters with optical density OD>5.
