摘要
Most few-cycle pulses are formed by compression of an ultrabroadband light source obtained in meter-long hollow-core fiber filled with noble gas [1]. However, the hollow-core fiber scheme requires a careful alignment and is extremely sensitive to the beam-pointing direction, limiting its long-term stability. Recently we reported a novel approach of using a set of plates for continuum generation (MPC, schematic is shown in fig. 1(a)) using 800 nm 28 fs pulses [2]. In this paper, we present a MPC generation scheme for driving with 1030 nm lasers that have pulse duration of as long as 170 fs. We demonstrate a spectrum spanning from 550 nm to 1250 nm, (bandwidth at -20 dB intensity) that is capable of supporting single-cycle pulses while maintaining good output beam quality.
