Diode-pumped 100-fs lasers based on a new apatite-structure crystal: Yb~(3+):SrY_4(SiO_4)_3O

摘要

We demonstrated, for the first time, sub-100-fs lasers based on an Yb-doped apatite crystal: Yb~(3+):SrY_4(SiO_4)_3O, also called Yb:SYS. Pulses as short as 94-fs have been obtained at 1070 nm with an average power of 110 mW. We also developed a regenerative amplifier based on this crystal, and obtained 100μJ, 420-fs pulses following compression.
