title: Diode-pumped tri-wavelength synchronously mode-locked Yb,Y:CaF₂ laser.
abstract: A tri-wavelength synchronous mode-locking operation of a diode-pumped Yb,Y:CaF2 laser has been investigated by using a semiconductor saturable absorber mirror at 1 μm. The tri-wavelength synchronous mode-locking pulses were centered at 1045.7, 1047.6, and 1049.5 nm. An interference pattern was obtained in the autocorrelation trace, where the beat pulse width was 3.2 ps and the repetition rate was 0.52 THz. The maximum average output power was 196 mW with pulse width 120 ps and repetition rate of 89 MHz.
