Abstract

Chirped-pulse amplification technique has been used extensively in the development of high-power ultrafast optical amplifiers since its first demonstration.¹ Due to various limitations, the reported average output powers in the past were generally at the 1 W level. Kilohertz repetition rates are preferred for the majority of ultrafast spectroscopy studies due to the better pulse-to-pulse stability and ability to use lock-in detection.
