The advancement of high repetition rate optical frequency combs (OFCs) is a major current effort in the photonics community and has seen rapid growth in recent years. However, current gigahertz OFCs such as electro-optic combs, microresonator combs, and Kerr-lens modelocked (KLM) Ti:sapphire lasers, all face many challenges that have required very difficult compromises in system complexity, cost, stability, repetition rate, and average power.

Here we introduce a new class of modelocked lasers which can overcome all these trade-offs.
