We report what is to our knowledge the first dual operation comprising laser action and Q switching of Cr4+:YAG pumped intracavity by a Nd:YAG laser. This technique produced dual 1.06- and 1.44-μm pulses with 35- and 200-ns pulse widths, respectively. The Nd:YAG rod was pumped by a 1-ms flash-lamp pulse, resulting in a train of 1.06- and 1.44-μm pulse pairs at approximately a 30-kHz rate.
