摘要：
A dual-off-axis pumping scheme is presented to generate orbital-angular-momentum (OAM) beam in Yb:CALGO laser. The OAM and wavelength can be actively controlled by the off-axis displacements and pump power with wavelength-tunable width about 10 nm and the OAM-tunable range from +/- 1h, to +/- 15h.
