Abstract
- A hybrid high energy femtosecond laser system based on Yb:YAG single crystal fiber amplifier is experimentally studied. Due to the low nonlinearity and high gain of the Yb:YAG single crystal fiber, laser pulses with high energy of 146 μJ at the repetition of 100KHz are obtained. The beam quality of 1.233 in the horizontal direction and 1.239 in the vertical direction is detected. After compression, pulses with the duration of 859 fs and energy as high as 63.5 μJ are achieved at 100 kHz repetition rate in a compact size, this compact and simple laser system will find various applications in ultrafast laser micro-machining.
