A diode-pumped continuous-wave Tm:YVO4 laser operating on the H34→H35 and F43→H36 transitions was demonstrated for the first time, to the best of our knowledge. An a-cut Tm:YVO4 crystal with 1.5% (atomic fraction) Tm3+ ion concentration was used to characterize the laser behavior. A common commercial laser diode with a central wavelength of 790 nm and a bandwidth of 3.2 nm was utilized as a pump source. With an output coupler for the H34→H35 and F34→H36 transitions, simultaneous three-wavelength laser operation was achieved. The laser emissions at 2292 and 2363 nm in π-polarization and at 2108 nm in σ-polarization were realized. With an incident pump power of 22 W, the total output power of 1.17 W at 2292, 2363, and 2108 nm was obtained. The output power at 2292 and 2363 nm was measured to be 750 mW, and the output power at 2108 nm was measured to be 420 mW.
