TLDR
In this article, the 3P0 - 3H6 transition around 613 nm has been shown to have a tunable linewidth of 1nm, which, for the first time, has allowed the direct production of femtosecond pulses in the visible from a cw solid state laser using Kerr lens mode-locking.Abstract:
Fourteen new cw, visible laser transitions have been observed in Pr3+:YLF, several of which have exhibited modest tunability. The 3P0 - 3H6 transition around 613 nm has been shown to have a tunable linewidth of ~1nm, which, for the first time, has allowed the direct production of femtosecond pulses in the visible from a cw solid state laser using Kerr lens mode-locking.read more
