In this presentation, we report on the demonstration of an OAM versatile tunable vortex laser with five OAM states ( based on a singly resonant optical parametric oscillator (OPO) formed of a non-critical phase-matching LiB₃O₅ (NCPM-LBO) crystal in an extendable linear cavity.Also, the wavelength of output can be tuned in a wavelength range of 0.74-1.87um . The mechanism of the system provides us new insights on the conservation of orbital angular momentum and numerous potential applications.
