“…A tunable (0.75-1.9 µm) optical vortex was achieved from a LiB 3 O 5 (LBO) singly resonant OPO [26,27]. A widely tunable (3-5 µm) optical vortex was obtained from a MgO:periodically poled lithium niobate (PPLN) or (KTiOAsO 4 ) KTA OPO [28][29][30][31][32]. A tunable 2 µm vortex laser output was also developed based on a KTiOPO 4 (KTP) crystal OPO [33][34][35].…”

We generate a tunable (2.3–3 μm) optical vortex output with an order of 1 or 2 from a 1 μm optical-vortex-pumped singly resonant parametric oscillator based on a Mg doped periodically poled lithium niobate crystal. The orbital angular momentum (OAM) from the pump vortex beam was transferred to the mid-infrared idler output in this signal singly resonant high-Q cavity configuration. A maximum vortex output energy of 1.52 mJ was achieved within a wavelength tuning range of 2.27–2.96 µm. The signal beam with the Gaussian spatial profile was also generated within a 1.66–2 μm tuning range. The wide spectral bandwidth was experimentally measured near the wavelength degeneracy and explained by theoretically.

“…98−100 for good reviews), we briefly highlight some interesting advances. These include intra-cavity geometric phase 101 for helicity control, spin-orbit effects 102 with high purity, vortex OPOs 103 to move into the mid-infrared, wavelength and OAM tuneable lasers 104 based on fibre geometries. Most of these solutions have been at low power.…”

The interest in tailoring light in all its degrees of freedom is steadily gaining traction, driven by the tremendous developments in the toolkit for the creation, control and detection of what is now called structured light. Because the complexity of these optical fields is generally understood in terms of interference, the tools have historically been linear optical elements that create the desired superpositions. For this reason, despite the long and impressive history of nonlinear optics, only recently has the spatial structure of light in nonlinear processes come to the fore. In this review we provide a concise theoretical framework for understanding nonlinear optics in the context of structured light, offering an overview and perspective on the progress made, and the challenges that remain.

“…Apart from compensating the walk-off effect with two cascaded crystals, the quasi-phase matching and non-critical phase matching without walk-off were widely used. For the quasi-phase matching, Yusufu et al [136] reported a tunable vortex laser based on the parametric source with a periodically poled crystal MgO: PPLN. A 1064 nm Nd: YAG laser was chosen as the seed light, and a spiral phase plate was adopted for tailing the pump light into a vortex beam.…”

Optical vortices are optical fields that possess a helical phase and orbital angular momentum, which have found the application in micromanipulation, optical communication, orbital angular momentum entanglement, super-resolution imaging, metrology, etc. The urgent need for the wide spreading applications of vortex lasers is to increase the wavelength versatility. In this study, the nonlinear frequency conversion of vortex lasers with a focus on sum frequency generation stimulated Raman scattering, and optical parametric oscillators were meticulously reviewed. The characteristics of the topological charge transfer and output beam profiles of different frequency conversion were discussed. As the precise tuning of optical fields in both temporal and spatial domains shall be the trend of future studies, it is our hope that this review shall serve as a reference for future research. Combining these techniques with the streaming methods to produce optical vortices, i.e., annular pump, off-axis pump, reflection mirror with defect spots, spherical aberration, and birefringence, it is advisable to expand the wavelength and fill the wavelength gap in the ultraviolet, visible, and infrared bands.
