Abstract

We explore the operation of spontaneous mode locking in a diode-pumped $\mathrm{Nd}\text{:}{\mathrm{SrGdGa}}_3{\mathrm{O}}_7$ disordered crystal laser. The first- and second-order autocorrelations are simultaneously performed to evaluate the temporal characteristics. An 80 GHz pulse train with a pulse duration as short as 616 fs is observed. The maximum output power is 415 mW at a pump power of 6.1 W.
