Fourteen new cw, visible laser transitions have been observed in Pr3+:YLF, several of which have exhibited modest tunability. The 3P0 − 3H6 transition near 613 nm has been shown to have a tunable linewidth of ~1 nm, which, for the first time to our knowledge, has permitted the direct production of femtosecond pulses in the visible from a cw solid-state laser by Kerr-lens mode locking.
