利用时间非色散光栅装置实现了飞秒脉冲的空间扩展和再压缩放大。所使用的系统不延长脉冲，提供比常规放大器更高的增益，并且有效地将放大的自发辐射从信号中分离。输出脉冲的持续时间很容易控制从τ（分钟）= 50 fs到几百飞秒的空间色散方案中使用的组件的微调。
Amplification of femtosecond pulses through spatial expansion and recompression in a temporally nondispersive grating apparatus is demonstrated. The system used does not lengthen the pulse, provides higher gain than conventional amplifiers, and separates effectively the amplified spontaneous emission from the signal. The output pulse duration is easily controlled from tau(min) = 50 fs to several hundred femtoseconds by fine adjustment of the components used in the spatially dispersive scheme.
