100 MHz chirped pulse and frequency comb laser source using an intra-cavity etalon and long-term stabilization

We present a semiconductor-based laser cavity operating in the extreme chirped pulse amplification regime using a 100 MHz fiberized Fabry-Perot etalon. An intra-cavity modified Hänsch-Couillaud scheme ensures long-term operation. The laser exhibits supermode noise spur suppression and a semiconductor-based optical frequency comb is generated.
