Frequency-doubled beam of the higher-order Laguerre-Gaussian mode is obtained with a high power (2 mW) aiming at an investigation of the interaction between the Laguerre-Gaussian beam and ions in a radio-frequency ion trap. For a sufficient beam power, the Hermite-Gaussian beam is obtained at first, frequency-doubled, and then mode-converted to the Laguerre-Gaussian mode. The beam profile is analyzed theoretically.
