报告摘要：  

Over the past several years, substantial progress has occurred in the development of mode-locked (ML) solid-state lasers emitting in the 1~2 μm spectral range based on Yb3+-, Tm3+- and Ho3+-doped or Tm3+ and Ho3+ co-doped crystals and ceramics, in particular towards femtosecond pulse generation. This advancement has been defined to a great extent by the availability of new host materials for these trivalent optically active rare-earth (RE) dopant ions. We discuss here essential requirements and properties of such materials for successful laser operation in the few-optical-cycle regime based on the 2F5/2 → 2F7/2 of Yb3+, 3H4→3H6 of Tm3+ and the 5I7→5I8 Ho3+ transitions and summarize more recent ML laser results.
