We demonstrated a widely tunable 1-μm optical vortex laser formed from a 0.532-μm optical vortex pumpedoptical parametric oscillator with a singly-resonant cavity configuration employing cascaded non-critical phase-matching LiB₃O₅ crystals. With this system, the topological charge of the pump beam can be selectively transferred to the signal or idler output, and a vortex output in the wavelength range of 850-990 nmor 1130-1300 nm could be obtained.A maximum signal vortex output energy of 0.9 mJ was achieved, corresponding to an optical efficiency of 10%.
