摘要

A double-pass noncollinear optical parametric chirped pulse amplifier has been demonstrated. The signal is double-pass amplified in a single nonlinear crystal by a nanosecond pump pulse. The first-pass optical parametric amplification is completely phase matched in the plane of the maximum effective nonlinearity, and the other pass works symmetrically near to the first-pass optical parametric amplification plane. This architecture efficiently increases the overall gain, overcomes the optical parametric fluorescence. This scheme has been used respectively in the optical parametric chirped pulse amplifiers which the signal is an Yb-doped passively mode-locked fiber laser or a Kerr lens mode-locked Ti:sapphire oscillator.
