Abstract

We present a kind of rotational two photon mciroendoscopy for 1μm fiber femtosecond laser. The fiber laser provide ultrashort femto-second pulses with center wavelength at 1.034μm and repetition rate of 50MH. The rotational probe is based on double cladding photonic crystal fiber (CD PCF) fiber, Grin lens , microprism and rotational MEMS motor. The MEMS motor has diameter of 2.2mm and can provide 360 degree full view rotation. We experimentally show that the DC PCF fiber works for 1μm fiber laser two photon system. Second harmonic generation (SHG) singnal line profile of rat tail tendon and fish scale was taken with the endoscopy system.
