摘要

Nd:玻璃放大器具有非常好的能量存储能力，但对于短脉冲放大，能量提取效率极低。在雷达领域工作的科学家们克服了类似的峰值功率限制，他们先发出啁啾，然后在放大之前拉伸脉冲。通过放大较长的脉冲，可以获得更高的能量。然后将回波压缩到约等于1/Δf的脉冲宽度，其中Δf是总频率啁啾。

Picosecond Pulse Amplification Using Pulse Compression Techniques

Nd:Glass amplifiers have very good energy storage capabilities, but, the energy extraction is extremely inefficient for short pulse amplification. Scientists working in the radar field overcame similar peak power limitations by first chirping and stretching the pulse prior to amplification.1-2 By amplifying the longer pulses, much higher energies could be achieved. The echo was then compressed to a pulsewidth approximately equal to 1/Δf, where Δf is the total frequency chirp.
