The inverse problem of amplification of broad-spectral-bandwidth laser pulse

By using the pulse-sequence model,the inverse problem of amplification of broad-spectral-bandwidth laser pulse has been studied,i.e.,to find the initial input temporal pulse profile,spatial profile,spectral distribution and fluence from the required output temporal,spatial pulse profile,spectral distribution and fluence as well as the given amplifier parameters. The results are useful for the design of high-power laser amplifiers.
