持续时间为几十飞秒的光脉冲用于驱动从原子科学到计量学的各种应用,但基于振动晶体或掺镱石英光纤增益介质的飞秒激光器仍然体积庞大且昂贵。尽管原则上带隙工程量子限制半导体材料在增益带宽和光谱多功能性方面具有显着优势,但迄今为止,半导体激光器还不能产生相对短的脉冲。在这里,我们描述了一种光泵浦 InGaAs/GaAs 量子阱激光器,它使用腔内半导体可饱和吸收镜进行被动锁模,发射 1,037 nm 的 60-fs 脉冲,光谱带宽为 20 nm(半峰全宽)。在这种激光器中,快速光学斯塔克自吸收调制和强增益饱和相结合,在载流子散射的时间尺度上形成脉冲。腔体包含一组稳定的循环脉冲,这些脉冲按饱和增益恢复时间固定的间隔有规律地间隔开。
Optical pulses with durations of a few tens of femtoseconds are used to drive applications ranging from attoscience to metrology, but femtosecond lasers remain bulky and expensive items based on vibronic crystal or ytterbium-doped silica fibre gain media. Although, in principle, bandgap-engineered quantum-confined semiconductor materials have significant advantages in terms of their gain bandwidth and spectral versatility, semiconductor lasers have not, to date, been capable of generating comparably short pulses. Here, we describe an optically pumped InGaAs/GaAs quantum-well laser that is passively mode-locked using an intracavity semiconductor saturable absorber mirror that emits 60-fs pulses at 1,037 nm with an optical spectrum bandwidth of 20 nm (full-width at half-maximum). In this laser, fast optical Stark self-absorption modulation and strong gain saturation combine to shape pulses on the timescale of carrier–carrier scattering. The cavity contains a stable group of circulating pulses, regularly spaced at an interval fixed by the time over which the saturated gain recovers.
