中文摘要
飞秒放大器的普遍困境是增益变窄(一个激光脉冲放大越多,其持续时间越长),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。傅里叶平面光参量放大器(FOPA)概念可以同时放大峰值功率、平均功率和放大的频谱带宽(维持低周期持续时间所必需的)。该装置可以在任何波长范围的传统放大方案中操作,然而,具有放大单光周期的能力。
英文摘要
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. The Fourier-plane Optical Parametric Amplifier (FOPA) concept enables simultaneous up-scaling of peak power, average power, and amplified spectral bandwidth (necessary to maintain few-cycle duration). The device can be operated at any wavelength range of conventional amplification schemes, however, with the capability to amplify single optical cycle of light.
