Abstract :
Optimizing high-power ultrashort pulse amplifier using double-clad Yb-doped fiber, maximum output power of >3 W with a pulse width of 110 fs without pedestal component is obtained. Using this pulse, high-power THz pulse generation is measured by a pyroelectric detector with a low sensitivity.
