Abstract

Newly developed Raman Notch Filters (RNF) were applied to the following cases:a. Using RNF as a pre-filter of a common monochromator to record Raman spectra of benzene, the exciting wavelength was the second harmonic generation of a Q-switched YAG pulsed laser (532 nm). b:Observing the stimulated emission due to the weak transition near 1.064 μm in a Q-switched frequency-doubled Nd3+:YAG laser with RNF as laser (532 nm) suppression apparatus. RNF can suppress the straylight at the laser wavelength by a factor of 108.
