We employed a high-repetition-rate quasi-three-level 912 nm pulsed laser as the gain-switched pump source, generated by an ${\rm Nd}\!:\!{{\rm GdVO}_4}$ laser gain medium and a ${\rm Cr}^{4 +}\!:\!{\rm YAG}$ saturable absorber. The 912 nm laser directly pumps the ${\rm Nd}\!:\!{{\rm YVO}_4}$ crystal within the resonator. For the first time, to our knowledge, we achieved a high-repetition-rate dual-wavelength twin-pulse laser output at 912 and 1064 nm without gain competition.
