Abstract:
An Yb:CaF2 laser pumped by two 400-mW single-mode laser diodes at 976 nm is reported to generate Fourierlimited
65-fs pulses, the shortest to date achieved with a semiconductor saturable absorber mirror (SESAM)
mode-locking and this laser material to date. With a multimode pump diode, we have demonstrated higher average
output powers of up to 1.4 W with 87-fs pulses. Key to these successful results was the implementation of
practical design guidelines allowing safe mode-locking operation without Q-switching instabilities, which appear
to damage the SESAMs more easily in Yb:CaF2 oscillators compared to other Yb-doped materials.
