Fiber-format stimulated-Raman-scattering microscopy from a single laser oscillator.
A highly simplified architecture for stimulated-Raman-scattering microscopy is demonstrated, where multiple tunable narrowband picosecond pulses are generated by spectral compression of femtosecond pulses emitted by a single compact Er-fiber oscillator. The system provides high sensitivity (2x10(-7)) and spectral resolution (sub-15 cm(-1)), and it offers an unprecedented flexibility for multicolor imaging.
