我们推出了一种飞秒垂直外腔表面发射激光器 (VECSEL)，其重复率可在 6.5 GHz 至 11.3 GHz 范围内连续可调。使用低饱和注量半导体可饱和吸收镜 (SESAM) 可以通过简单的腔设计实现稳定的连续波锁模，SESAM 和 VECSEL 上的激光模式面积相似，并且不会因腔长度的变化而发生显着变化。在整个调谐范围内，无需对腔体进行任何重新对准，脉冲持续时间在 625 fs 左右几乎保持恒定，标准偏差小于 3.5%。中心波长在963.8 nm附近仅变化±0.2 nm，而输出功率为169 mW，标准偏差小于6%。这种可调谐重复率对于各种计量应用都很有趣，例如激光腔调谐光学采样（OSCAT）。
We present a femtosecond vertical external cavity surface emitting laser (VECSEL) that is continuously tunable in repetition rate from 6.5 GHz up to 11.3 GHz. The use of a low-saturation fluence semiconductor saturable absorber mirror (SESAM) enables stable cw modelocking with a simple cavity design, for which the laser mode area on SESAM and VECSEL are similar and do not significantly change for a variation in cavity length. Without any realignment of the cavity for the full tuning range, the pulse duration remained nearly constant around 625 fs with less than 3.5% standard deviation. The center wavelength only changed ±0.2 nm around 963.8 nm, while the output power was 169 mW with less than 6% standard deviation. Such a tunable repetition rate is interesting for various metrology applications such as optical sampling by laser cavity tuning (OSCAT).
