摘要：

Diffractive optics are used to ere-ate low- and high-order Laguerre-Gaussian (LG) beams from the output of a diode laser. We examine the mode parities, conversion efficiencies, extinction ratios, and propagation characteristics. We present detailed analyses of the beam profiles for one- low-order (LG(0)(1)) and one high-order (LG(1)(2)) Laguerre-Gaussian mode. Modeling the LG(1)(2), beam as a superposition of LG modes, we find (99.3 +/-0.9%) of the laser intensity in the LG(1)(2) mode, a mode purity greater than for LG beams created by other methods external to the laser cavity. The high mode purity may be useful in making atom traps for precision measurements and, for Bose-Einstein condensation.
