The universal dilemma of femtosecond amplifiers is gain narrowing (the more one amplifies a laser pulse, the longer gets its duration) which prevents ultra high power lasers from delivering few-cycle pulses. To overcome this problem, a new amplification concept is proposed. It enables simultaneous up-scaling of peak power and amplified spectral bandwidth (necessary to maintain few-cycle duration). The Fourier plane Optical Parametric Amplifier - FOPA can be operated at any wavelength range of conventional amplification schemes, however, with the capability to amplify a single optical cycle of light.

飞秒放大器普遍面临的困境是增益变窄（激光脉冲放大得越多，其持续时间就越长），这阻碍了超高功率激光器提供少周期脉冲。为了克服这个问题，提出了一种新的放大概念。它可以同时提高峰值功率和放大的光谱带宽（维持少周期持续时间所必需的）。然而，傅里叶平面光参量放大器 - FOPA 可以在传统放大方案的任何波长范围内工作，并且能够放大单个光周期。
