Abstract
We demonstrate a diode-pumped picosecond Yb-doped silicate Yb3+:Sc2SiO5 (Yb:SSO) chirped pulse amplifier. The seed source with a pulse width of 220 fs is a diode-pumped Yb:KGW femtosecond oscillator. A single chirped volume Bragg grating is employed both as a pulse stretcher and as a compressor to improve the compactness of the system. Stretched pulse is amplified using a diode-pumped Yb:SSO regenerative amplifier. The maximum amplified pulse energy obtained at a pump power of 13.5 W is 450 μJ. The amplified pulse is centered at 1033.3 nm before compression at a frequency of 1 kHz. After compression, the pulse energy is 315 μJ with a pulse duration of approximately 1 ps.
