A compact, turn-key platform for multiplex stimulated Raman scattering microscopy

摘要: We combine an all-fiber dual wavelength, self-synchronized laser and a dedicated multi-channel detection unit to perform state-of-the-art multiplex Stimulated Raman Scattering (SRS) microscopy. The system covers the full CH spectrum in 1 μs reaching shot-noise limited performances with 25 μW per detection channel. This all-inone solution is based on a passively synchronized dual-wavelength laser source with shot-noise limited relative intensity noise from 600 kHz and a modular multi-channel lock-in detection unit. The synergistic design between laser source and detection system simplifies multiplex SRS implementation for real-time full-chemical imaging.
