Coherent’s 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) THz-Raman® spectroscopy, and other demanding spectroscopy or metrology applications. Incorporating NoiseBlock™ ASE Suppression Filters and configured for fast, easy alignment and use with SureBlock™ XLF Series Raman Filter Systems, the CleanLine™ family is based on Coherent’s proprietary solid-state, ultra-narrow band Volume Holographic Filter technology, delivering unlimited lifetime, exceptional throughput, and ultra-stable environmental performance.
The CleanLine™ FS free-space filter system is an ultra-compact (3 inch or 75 mm) filter system with integrated alignment irises and a built-in wavelength fine-tuning adjustment. The CleanLine™ LM-FS incorporates a SureLock™ LM Series wavelength-stabilized laser module along with a CleanLine™ FS. And the CleanLine™ LM-FC includes an optical isolator and various fiber-coupling options – making the CleanLine™ easily configurable for turn-key integration into your experiment, instrumentation, or Raman spectroscopy system.
Available for standard wavelengths of 785 nm, 532 nm, and 405 nm. Custom wavelengths are available upon request.
