Gain narrowing effect
WebOct 19, 2024 · By balancing the gain-narrowing effect with self-phase modulation during the amplification, we achieved an average output power of 11 W, corresponding to a pulse energy of more than 1 µJ. The pulse duration can be compressed to sub-50 fs behind the amplification stage. WebMay 29, 2024 · However, gain narrowing significantly reduces bandwidth during the amplification process, and thus it is difficult to achieve a shorter pulse duration. Shorter pulse durations in CPA regenerative amplifiers have been demonstrated by reducing gain narrowing in two ways: intra-cavity and extra-cavity.
