Popis: We demonstrate a highly multimodal nonlinear micro-endoscope for real-time, label-free imaging of biological tissues. The endoscope can perform two and three photon excited fluorescence, second, third harmonic and CARS imaging for different excitation wavelengths. Ultrashort pulses are delivered to the sample by a double-clad antiresonant hollow core fiber over the 800-1800 nm spectral band. The fiber tip is placed into a doubly resonant piezoelectric tube which allows a spiral scanning on the sample. The endoscope distal head containing the scanning device and the GRIN micro-objective is 1.5 mm in diameter and 35 mm long. Real-time nonlinear imaging at 10 frame/s is demonstrated.
