Selective Excitation of Higher-radial-order Laguerre-Gaussian Beams Using a Solid-state Digital Laser

In this paper, we use a digital laser to generate high-radial-order Laguerre-Gaussian, LGp,0 modes by loading digital holograms on a phase-only spatial light modulator that act as an end mirror of a diode-end-pumped laser resonator. The digital holograms were encoded with an amplitude ring mask, which contained absorption rings that match the p-zeros of the Laguerre polynomial. We demonstrate the generation of high-quality LGp,0 modes with a mode volume that is directly proportional to the mode order, p. This work demonstrates the possible of using the digital laser as a tool for simulating optical elements that will be used in pursuing high brightness lasers. p Lp(X) 0 1 1 1-X 2 X2/2 − 2X + 1 3 −X3/6 + 3X /2 − 3X + 1 Table 1: Laguerre Polynomials.
