Thin-film lithium niobate microresonator Raman lasing suppression methods and octave-spanning frequency combs. a, Thin-film lithium niobate microresonator Raman lasing suppression methods, including ...
Laser frequency combs, sources with a spectrum consisting of hundred thousands evenly spaced narrow lines, have an exhilarating potential for new approaches to molecular spectroscopy and sensing in ...
Sound-level measurements offer a conventional way to measure sound but do not contain frequency information, making it difficult to compare different sounds or vibration. Octave analysis filters the ...
