Regenerative pulse-shaping techniques and their applications on the amplification of sub-20 fs or two-color femtosecond pulses Academic Article uri icon


  • One of the fundamental limitations of chirped-pulse amplification systems has been their limited amplified bandwidth due to the gain-narrowing effect. To increase the spectral throughput of these systems, a series of novel regenerative pulse-shaping schemes was developed. These systems can overcome the gain-narrowing problem and amplify the seed pulse to the mJ energy level and produce bandwidth as great as 90 nm. To date, by using these techniques in conjunction with a four-pass post amplifier, have produced multiterawatt, 18-fs pulses. The technique simultaneously amplified and compressed two femtosecond pulses separated by as much as 100-nm in wavelength.
