WebAug 20, 2024 · Abstract. We demonstrate a tunable external cavity tapered amplifier laser (ECTAL) using a narrowband interference filter as the wavelength discriminator. The laser … WebThe laser line bandpass filter is placed in the optical path between the laser and the sample. This ensures that any external ambient light is blocked and only the laser line wavelength is passed. After the light is incident on the sample, it is shifted due to Raman scattering and contains many low intensity modes or signals.
