Laser Wavelength Purification Filter
Laser wavelength narrowband filters can be divided by their half bandwidth into general laser wavelength filters and laser line-cleanup filters. The former are mainly used in application scenarios insensitive to stimulated emission noise near the laser wavelength, such as when the laser serves as a fluorescence light source; the latter are mainly designed for gas and solid-state lasers to eliminate spontaneous emission noise, such as in Raman spectrometers and medical laser systems.
