Soliton mode-locked Nd:YAlO_3 laser at 930 nm

Abstract

We report on a soliton mode-locked Nd:YAlO3 laser at 930 nm. We used a semiconductor saturable absorber mirror and a Gires–Tournois Interferometer for dispersion compensation to achieve soliton mode locking. The generated pulses were as short as ΔτFWHM = 1.9 ps with a spectral bandwidth of Δλ=0.5 nm. The pulses were almost transform limited assuming a sech2 pulse shape. The averaged output power was 410 mW at an absorbed pump power level of 1.76 W. An investigation of the effect of the third-order dispersion of the Gires–Tournois interferometer on the spectra of the mode-locked laser is presented.
