Abstract

We demonstrate rapid switching between picosecond and femtosecond operational regimes in a Cr4+:forsterite laser, using an electrically-contacted GaInNAs SESAM with saturable absorption characteristics controlled via the quantum-confined Stark effect. Additionally, continuous picosecond pulse duration tuning by over a factor 3 is reported. (C) 2012 Optical Society of America
