NoiseBlock™ ASE Filters and Beamsplitters and CleanLine™ Filter and Laser Systems

NoiseBlock™ ASE (Amplified Spontaneous Emission) Suppression filters suppress the broad spectrum of spontaneous emission that commonly occurs in laser diodes to provide a pure, ASE free, single frequency laser. The NoiseBlock™ 90/10 Beamsplitter Filters utilize the same narrow-band VHG technology, and are designed to diffract 90% of the incoming light that matches the designed Bragg wavelength and incident angle. All other wavelengths will be transmitted through the filter, making them excellent for boosting the effective signal of a Raman spectrometer. And the CleanLine™ Series ASE Filter Systems are a family of tightly integrated, pre-aligned, multi-element ASE Filter Modules designed to provide the enhanced narrow band, low noise, ASE-free laser performance required for ultra-low-frequency (low wavenumber) Raman spectroscopy, and other demanding spectroscopy or metrology applications.
