Abstract

We experimentally demonstrate the generation of sub-100-fs pulses from a diode-pumped passively mode-locked Yb:Y3ScAl4O12 (Yb:YSAG) ceramic laser. Stable mode-locked pulses as short as 96 fs at the central wavelength of 1052 nm with a repetition rate of ∼102 MHz are obtained. The laser has a maximum average output power of 51 mW. To the best of our knowledge, these are so far the shortest pulses and the first demonstration of sub-100-fs pulses obtained from the mode-locked Yb:YSAG ceramic lasers.

To the best of our knowledge, demonstrated the passive mode-locking of a 15 at.% Yb:Y3ScAl4O12 (Yb:YSAG) ceramic chip in 2004, which generated 280 fs pulses with an maximum average output power of 62 mW[15]

Summary

Introduction

We experimentally demonstrate the generation of sub-100-fs pulses from a diode-pumped passively mode-locked Yb:Y3ScAl4O12 (Yb:YSAG) ceramic laser. They achieved stable mode-locked pulses with a 615 fs pulse width and 420 mW average power in a diode-pumped Yb:Y2O3 ceramic laser.
