1.0-1.7- \mu m Wavelength-Tunable Ultrashort-Pulse Generation Using Femtosecond Yb-Doped Fiber Laser and Photonic Crystal Fiber

A widely wavelength-tunable ultrashort-pulse fiber-laser source has been demonstrated using a high-power mode-locked ytterbium (Yb)-doped fiber laser and a highly nonlinear photonic crystal fiber (PCF). The Yb-doped fiber laser produces 66-fs ultrashort pulse at the wavelength of 1.05 mum. The pulse...

Description
Summary:A widely wavelength-tunable ultrashort-pulse fiber-laser source has been demonstrated using a high-power mode-locked ytterbium (Yb)-doped fiber laser and a highly nonlinear photonic crystal fiber (PCF). The Yb-doped fiber laser produces 66-fs ultrashort pulse at the wavelength of 1.05 mum. The pulse energy and the peak-power are 2 nJ and 20 kW, respectively. By injecting this pulse into the highly nonlinear PCF, soliton and anti-Stokes pulses are generated in the wavelength regions of 1.05-1.69 and 0.6-0.7 mum, respectively. The generated soliton pulse is 100-150-fs transform-limited sech 2 -shaped pulse
