Nonlinear frequency conversion of structured beams has been great interest recently. We present an intracavity second harmonic generation (SHG) laser in transverse mode locking (TML) states with a specially designed sandwich such as microchip laser. The nonlinear process beam TML state to its is theoretically and experimentally investigated, considering different relative phase weight parameters between the basic modes beam. Comparison far-field SHG patterns fundamental coherently locked...
Optical lattices (OLs) with diverse transverse patterns and optical vortex (OVLs) special phase singularities have played important roles in the fields of atomic cooling, particle manipulation, quantum entanglement, communication. As a matter consensus until now, OL are generated by coherently superimposing multiple modes fixed difference through mode locking (TML) effect. There dark area this kind pattern, so it is also called OVL pattern. However, our research, found that some high-order...
The selective generation of laser transverse modes by gain regulation with a digital micromirror device (DMD) is presented in this letter. medium adjusted the switch patterns loaded on DMD. Structured pump beam can be obtained after reflection DMD, and then it's defocused into microchip short focal lens, so that transferred to regulate distribution. Corresponding structured beams generated system. pattern regulated easily quickly, switching Through method, we show simple flexible system...
