Mode locking of laser oscillators by injection-locking

Abstract
The possibility of mode locking of high‐powered laser oscillators by injection locking to a weak mode‐locked signal from a cw laser is proposed and demonstrated. The experiment was carried out using a flash‐lamp–pumped pulsed dye laser injection locked to a mode‐locked cw dye laser. Gains on the order of 3×104 and nearly Fourier‐transform–limited mode‐locked pulses were obtained.
