Abstract

We developed an octave-band tunable optical vortex laser based on a 0.532-μm optical vortex-pumped optical parametric oscillator with an extended cavity configuration by employing cascaded non-critical phase-matching LiB3O5 crystals. The optical vortex output was tuned within a wavelength range of 735nm-1893nm, and a pulse energy of 0.24-2.36 mJ was also achieved.
