Paper Abstract

We demonstrate a highly efficient and low threshold passively mode-locked femtosecond Yb:KYW laser pumped by an InGaAs narrow-stripe laser diode and which incorporates a semiconductor saturable absorber mirror. Near-transform limited pulses of 123fs at 1047nm were produced at an average mode-locked power of 107mW for only 308mW of incident pump power. An optical-to-optical conversion efficiency of 35% was achieved and the corresponding electrical-to-optical efficiency exceeded 14%.
